If you add a new device in your vehicle, you must tackle the task of providing the correct type of power to the device and potentially supplying that power via a hardwired connection to your vehicle's fuse panel.
This video discusses what the various power source types are (switched, switched - with retained accessory power, unswitched), shows you the common fuse and fuse tap types on the market today and it has examples of locating a fuse socket in a fuse box to use with a fuse tap.
🔷Another "easier" way to test for fuse socket power and avoid using the 1/2 fuse testing approach is to use the fuse tap itself with a fuse in the top fuse socket of the fuse tap. In this approach, you test for power by inserting the fuse tap and then checking for power at the end of the red wire coming out of the fuse tap (as shown at 11:00 in the video). If you don't have power with the fuse tap in that position, rotate the fuse tap 180 degrees and test again. Once you find the correct orientation for the fuse tap in the fuse socket, you can install the original fuse from the fuse box fuse socket in the lower fuse socket of the fuse tap. If there was no fuse in the fuse box fuse socket then you should not have any fuse in the lower fuse socket of the fuse tap.

Additional video on this topic. *Anatomy of An Automotive Fuse Tap* ruclips.net/video/YNc0FfeL6rw/видео.html
🔷Most fuse taps come with a 16 awg or 14 awg wire (smaller wire awg number is a bigger wire which can carry more current) to supply power to the new accessory. The awg wire size / gauge will be a limiting factor as to the max amperage that can be supplied safely via this fuse tap. In most cases, this means a 10 amp fuse is likely to be the maximum fuse amp rating you can use for the new accessory. If the wire from the fuse tap is quite long, the maximum fuse amp rating may be reduced even further.
🔷If you need to add a high amp draw power circuit to supply power to a new accessory, you may want to consider using a fuse tap to supply power to a switched power relay (with a fuse in the relay or in the other power circuit where the relay gets the power for the new accessory). The fuse tap power (switched power or switched with RAP) can supply power to the control side of the new relay. When the fuse tap supplies power to the relay, the relay closes the circuit and the relay then supplies power to the new accessory from the power source the relay is connected to with an appropriately sized fuse and wire awg being used for that power circuit.
🔷At 5:43 in the video I mentioned that you need to have the ignition switch in the appropriate position to make sure it provides the required power type (switched, switched with RAP or unswitched). To find a switched power fuse socket, you must start off with the ignition switch off and locate the candidate fuse sockets that don't have power, then turn on the ignition switch to see if the fuse socket does receive power at that point. If you need a switched power with RAP capabilities fuse socket, you would need to turn off the ignition switch leaving the retained accessory power feature still active and then test the fuse socket again to make sure it was providing that type of power.
Thank you for your suggestions, they are very helpful.. Not only BlackVue B-124X battery pack does not provide Low-profile Mini fuse taps with the battery , but also in the user manual does not talk about as to what gauge of low profile mini fuse tap one should buy separately...
There are different websites selling low profile mini fuse taps, but all of them have different awg...
for example:
BlackVue provided fuse taps(Ato, Micro2 & Mini) have this awg: 14awg 600v 1015 105'c awm
other seller #1: 16awg 600v 1015 105'c awm (low profile mini fuse taps)
other seller #2: 18awg 600v 1015 105'c awm (low profile mini fuse taps)
Gauge - depicts the amounts of load/current a wire can handle safely..
could you tell me, what gauge of a low profile mini fuse tap i should get....out of these three given below
14 gauge fuse tap wire can safely transmit 15-18 amps
16 gauge fuse tap wire can safely transmit 10-13 amps
18 gauge fuse tap wire can safely transmit 7-10 amps
In my vehicle's interior fuse box, these are the switched accessory fuses I found.. would you please help locating a fuse that is not critical to the power... can't figure out which one is the right one..
1) [20A - WIP RR(RearWIndowWiper)], 2) [10A-EPS IG],
3) [15A-WASHER RR(RearWindowWasher)], 4) [20A-WASHER(WinshieldWasher)],
5) [10A-ECU IG NO.3], 6) [10A-HTR-IG(AirConditionSystem)],
7) [7.5A-GUAGE NO.2(Guages&Meters,MultiInformationSystem)],
8) [15A- S-HTR FL(SeatHeaterLeftSide)], 9) [15A- S-HTR FR(SeatHeaterRightSide)],
10) [15A- P/VENT(PowerQuarterWindows)],
11) [7.5A- WIP ECU(WindshieldWiper&RearWindowWiper)],
12) [15A- STRG HTR],
Thank You for all your help..
The wire gauge (awg) governs two factors - amperage it can carry for a particular distance. I would recommend getting the lowest awg value possible. A lower awg number is a thicker wire that can handle higher current loads. Of the three mentioned, the 14 awg can carry the most current/amps for the longest distance.
The fuse sockets you listed have a few potential sockets that can be used. Stay away from any fuse socket that supplies power to an "... ECU". The "EPS IG" fuse appears to be for the electric power steering so stay away from that one. Any of the "SeatHeater....." fuse sockets might be a fuse socket that can be used. The "STRG HTR" fuse socket looks like a heated steering wheel so it too is a decent candidate. All of the heater fuse sockets have a 15A fuse in them so the max fuse I would recommend is a 15 amp fuse for the new accessory (B-124X). This is assuming there are no empty fuse sockets available in the fuse box that have switched power.
@@RetroCarGuy530sorry for bugging you with questions... Just noticed that I Do not have Heated Seats in my vehicle, but there are already fuses(15A fuse in each slots) for them in my interior fuse box. just wondering why these fuses r there when my cloth seats have no such options or buttons to turn them on on my dashboard/instrument panel..
As per your suggestion and as far as the orientation of fuse taps go, S-HTR FL & S-HTR FR are both viable candidate for tapping fuses into them without blocking fuse box cover in the way...
Since i have heated seat fuses 15A each & they are not operational (No Current Draw).. so Should I go with 15A fuse(Bottom Slot of the fuse tap) WITH 10A? OR 15A? or 20A? (Top Slot of the fuse taps)... Thank You!!
Sorry I didn't reply sooner, RUclips doesn't present replies to comments in a manner that is easy to see.
If there is a fuse in the fuse socket, it would suggest that something is being powered by the power from that fuse. It is certainly possible that those fuses/fuse sockets are leftovers from a version of that vehicle with the seat heaters.
The "safest" approach would be to put the 15A fuse in the bottom slot of the fuse tap and up to a 10A fuse for the new accessory powered by the fuse tap. I like to limit the max draw from a blade fuse style fuse socket to 25 amps (some say 30A is ok).
If you're 100 percent sure there is nothing being powered by the pre-existing 15A fuse or fuses, you could simply leave the 15A fuse out of the bottom socket of the fuse tap and you could in theory put up to a 20A fuse in the top slot (if the fuse tap and other wiring to the accessory will support 20 amps).
There are three main factors that go into the max fuse amperage size for the new accessory (amperage already supplied by the fuse socket, wire gauge of fuse tap and wiring to the new accessory including its ground wiring and the length of the wiring used for the new accessory). If you haven't watched my FAQ video I created in the past week or so, you might want to check that out where I try to identify the questions / answers that one needs to figure out when trying to size the max fuse amperage size for a fuse tap. ruclips.net/video/DnZ5wb_A5vE/видео.html
I hope this answers your questions.
@@RetroCarGuy530 Thank you for going extra mile in helping people... very informative youtube video....
This is literally the only video I could find that actually left me feeling confident by the end. The density of knowledge here spares no expense to the thoroughness of it. Thank you, you got me over a major hurdle here.
YES, this is the video!
To all of the people who had already watched several other tutorials on fuse tapping and still have questions.
This video will answer all of them👍
I watched about 6 videos trying to figure this out before coming here, yours is the one i needed, thank you.
Was about to post exactly this. Thank you!
DITTO! I am trying to wire up a dash cam on my bike and man oh man did this solve my problems and answer my questions!! Thank you so much good sir
I watched 1 week of videos, and this video does explains it the best!
Finally someone who knows what they're talking about. All the other videos just tell you to slap the add a circuit in.
Thanks for explaining the difference between tapping into a fuse that’s already there and tapping into a open slot that may have power and how not to put a fuse in the bottom of using a open slot. I couldn’t really find information on that.
Glad it helped
Yeah, I came here looking for the very same information. Thank you for the useful video.
Finally a professional, all of the other videos they’ll mention “ I’m no mechanic and I’m no electrician”
I know this video is a year old now but I wanted to say thank you. I've hardwired many things in the past but never with a "tap a fuse". I hardwired a dash cam with motion sensor and couldn't figure out why it wasn't working. I had one of the "tap a fuse" facing a different direction than the other for wire tidiness reasons. After seeing this video I slapped my forehead. Duh of course the power is only coming from one side or the fuses would be pointless. Thank you for saving my sanity.
I have watched dozens of videos about fuse taps. Yours is the most concise, logical and easy to understand. Thank you for posting this excellent presentation.
Damn, finally. I’ve been trying to figure out for days what to do with the lower portion of the fuse tap, since the fuse box socket had no original fuse. Thanks man, great work!
Amazing video. I think most of people (me included) thought the add-a-fuse could go either way while orientation is key. Otherwise you will have both devices on the lower fuse shoulders and likely to blow. My tip to check the orientation (might be easier). Plug the add-a-fuse ONLY with the top fuse inserted (leave the bottom slot empty). Plug it in. If you have 12 output from the red cable you are good. Otherwise you need to twist the add-a-fuse upside down. Once orientation is correct add the bottom fuse if needed. Should make sense.
This has come up a few times in the comments since I released this video in Dec 2019. I totally agree with your recommendation. I've updated the video's description section with this approach and there's a brief demonstration of this method at 11:00 in the video where I'm testing for power, but that was after testing with the 1/2 fuse. Thanks for the suggestion!
Yup. Easy way to determine which way to plug in.
The best break down ever.
Excellent video, great instruction. Concise and complete. You obviously not only know your craft but also how to teach it. I wish more did.
I've been collecting info from all sorts of fuse tap install info vids so I can make my own "complete" video to share with a friend.
You just took care of that here. I need to do nothing more. I'm sending your video right over to him.
Thank you, sir.
I've never used a fuse tap and just assumed you would just plug it in and go but I never thought about orienting it for the power to always go through the fuse for the fuse to do its job. Makes perfect sense. I'm glad I watched this video.
Very good. Very professional. Visually steady and clear. Thanks!
You addressed EVERY question I had as I prepare to add accessories to my Jeep. Thank you.
This was so much clearer than any diagram or video I could find. I now feel confident I can install my dash cam and have it wired properly for safety. Thank you.
I'm glad it helped. There are a couple of different trains of thought on this topic of using a fuse tap to obtain power for a new device/accessory. What I demonstrate in this video is the "in parallel" approach of routing the power through the fuse tap. The power obtained from the fuse box fuse socket is directly routed to both the lower and upper fuse sockets in the fuse tap.
There's another approach which would be labeled "in series" power routing approach. That's where the power from the fuse box fuse socket goes up the right leg of the fuse tap, through the lower fuse in the fuse tap and then down the left leg of the fuse tap to the original fuse box fuse socket and it also goes then up to the fuse tap's upper fuse socket. All of the power load runs through the lower fuse in the fuse tap. Which approach is best to use will result in spirited discussion/debates. The "in series" power routing method can be seen as the absolute safest approach, but it may also lead to blowing the original fuse in the lower fuse tap fuse socket since both power loads are being run through the lower fuse.
For dash cameras, radar detectors and similar power demanding devices (usually 2 amps and very often dash cameras use less than 1 amp), the "in parallel" power routing approach is very safe. It will only be adding 2 or often less than 1 amp to the circuit that is supplying the power to the fuse box fuse socket.
Thanks for checking out this video!
I have another video that tries to explain the "in parallel" approach a little more in depth. ruclips.net/video/YNc0FfeL6rw/видео.html
Absolutely the best tutorial video about hardwiring a dash camera. Saved me a lot of time and more importantly not burning up my device. Thank you.
Glad it helped!
This is far and away the best video on YT for this subject - well done!
I'm glad you found it helpful!
Best video about this and it’s not even close! You’ve earned my like and subscription for prompt responses to ALL of your viewers you really are amazing
Thank you so much!
Thank You! After watching the product I am installing and reading reviews, your video tied it all together
So well done. Makes the entire process so much easier to understand. Thank you Sir!
You're very welcome!
The best description and detailed explanation I have found to add an accessory switch for my vehicle. TY
Awesome, thank you!
Finally someone who knows how to give a presentation
FINALLY! Someone explained it and detailed it so I can understand! Thank you!
by far the most informative video, the visual demonstration is easy to follow (everything focuses correctly!) for beginners like me. Thank you so much for teaching!
Honestly that was such a well explained video
Absolutely amazing explanation. Very detailed. Appreciate your help!
Thank you. Helped a lot. USB charger installed properly and working.
Most helpful comprehensive video for my hardwire project!
Glad you liked it!
The best tutorial regarding the fuse tapping ! Thanks a lot 🙏
This really clarified a few things. Thank you!
Appreciate your explanation on fuse taps ! I am currently hard wiring dash cams on a couple
of cars - one has an empty slot with power, the other one - I will have to pull the fuse, add the tap & reinsert
the original & accessory fuse. I had no idea about the order these fuses went in - until watching your fine
tutorial. Thanks again !!!
Finally someone who explained it where I can understand and went into depth. Thanks.
I'm glad it was helpful!
Excellent video. Lots of videos out there don't tell you that it matters which way round the fuse tap is plugged in.
Good video. I appreciate the accurate language, definitions, and clarity.
Super helpful explanation of how to determine which side of the fuse slot has 12v to make sure the tap is oriented correctly. I also learned that fuses have the exposed metal on too for probing. I have never noticed that before!
Glad it helped
I too watched multiple videos and multiple web sites with no answer to my questions. THANK YOU , THANK YOU, THANK YOU!!!!!!!!!!!
My questions were:
1. Which side is the hot side on a fuse tap. Others glossed over it. You were very precise with pictures and typed out what is what.
2. If I could use only one fuse for the cb add on I wanted to use.
3. That I could use on open slot. And how to use it.
Thanks again!
I'm as slow as molasses, when it comes to Algebra and electronics, but the way you explain the steps, it seems I learn more from you than any other RUclips channel, therefore I've subscribed. Good luck on teaching this old man, a new subject.
I'm glad you found the video helpful. If you haven't already watched the FAQ video I made last summer on this topic, it might be worth the time to take a look at that video as well. ruclips.net/video/DnZ5wb_A5vE/видео.html
This is the best tutorial l've ever seen on RUclips.
superb , really well explained, loving it
the best video on youtube about fuse tap, even for me who doesn't really understand english. thank you very much !
You are welcome!
Excellent and informative and very fine details ... what a guy, awesome content like Scotty but with much less shouting 😂
THE BEST VIDEO ON RUclips FOR ADD A FUSE INFO!!!! Thanks
Glad you liked it!
Thank you sir. Why this wasn't the first recommend video I'm not sure. You answered everything clear and concisely.
Glad it was helpful!
Awwesome video, this is the best one on the subject! fuse taps!
The best explanation video I've seen on RUclips. I subscribed thank you
Really good video, simple, straight forward and explanatory, nice job.
Thanks! I'm glad you found it helpful.
A great example of testing and procedure. Hi from England 👍👍
Thank you for explaining so anyone can do it! Very informative!
Very good video. I don't know anything about electrical and I used a lot of points in this tutorial to install my underglow kit today. Thank you! No more Rocker Switches.
Glad it was helpful!
This is a well done video. Thought out well and is very easy to understand. I have a Amp for a speaker system.
I went into it to make a few gain adjustments and found that the Alpin light on the Amp has been on, charged, for 6 years.
I did find the proper fuse that only foes on when the ignition is turned on. all is well now. TY. Never knew they had piggy back fuses ...:)
Thanks! I'm glad you found the information helpful in solving your amp's power issue.
thanks. most informative out of several videos I have seen
Just phenomenal work. Very informative video. Thanks!!!
Excellent video and the best and direct explanations I've seen on this topic.
RUclips needs video's like this. To the point and very informative. Thank you! This is exactly what I needed.
Awesome video! thank you for sharing your knowledge to all of us.
excellent! complete and concise info on what i'm trying to work on. that half a fuse trick is good.
Glad you liked it! I show an alternative approach in another fuse tap video on my channel where I use the entire fuse in the upper fuse tap fuse socket. ruclips.net/video/YNc0FfeL6rw/видео.html
Gr8 video, just subscribed.
Finally i found a video that expains it, I was so confused, now I am educated.
Thanks
Clear and concise...well done and keep up the good work.
Greetings from England
Beautifully done, thanks bru!
Very informative! Exactly what I needed. Thank you!
Glad it was helpful!
Amazing video, very well explained!! Thank you
Very well explained,thanks you very much and happy new year.
Great tips, thank you very much, already put it in practise!! :D
Thanks a lot, some people are masters of teachings, you are one of them!!
So nice of you to say that.
Crystal clear and to the point. Many thanks for you time and effort
Glad you liked it
Thank you so much brother! Liked and subscribed!
Thank you so much for your explanation, and cutting the fuse in half that was very smart, now I was able to get the connection right.👍
Glad it helped. I demonstrated any even easier approach in one of my other videos. You don't have to cut any fuses for the alternative approach. ruclips.net/video/YNc0FfeL6rw/видео.html
Thank you for this. Was trying to install a hardwire for a dashcam in the interior fuse box of a 2022 honda accord and I have blown 2 multi block fuses when just using a test light probe to find which side the power was on. The second time I was very careful, but once I touch one side of the contact, it arced. Not sure what I'm doing wrong but I like the idea of using the half fuse for a testing.
Excellent! I learned a lot from this video. Thanks.
thank you for the explanation is very useful especially for me who often use fuse tabs like this in the work of a vehicle ...
Glad it helped
Thank you for this great video, I was so lost about how add on fuse work.
I'm glad it helped! I created a couple of additional videos to help further/better explain this topic.

thanks! that was very clear and informative!
Great and Fantastic Tutorial. Much appreciated.
Glad it was helpful!
Great video. Exactly what I needed to learn.
Great to hear!
Thank you RetroCarGuy
Excellent video. Thank you. Clear and concise instructions and extremely informative. I would've loved you to explain the joining the wires of a device to the fuse tap (cb radio) also I hope you have a video on using multimeters. I'm gonna go look for one now. Also you got yourself a new subscriber 👍
The fuse taps often come with crimp style butt connectors that you would strip the wire on the accessory side of the connection and insert and crimp the butt connector to get a firm grip on the wire. If no crimp butt connector is present, I will often solder the wires together use some wire shrink wrap or electrical tape to seal/protect the connection.
Awesome explanation thanks a lot for sharing 🙏👍
Brilliant’! Thank You for the video
Very informative video!! THanks
Very helpful video! Thank you
excellent video easy understanding . saved my time . appreciated you time and effort
