David- This was a fine piece of work, and your 2-part video is the ONE video that rules ALL ground wire by-pass videos on RUclips, of which there are many (and poorly done). Your detailed info helped me correctly solve my Silverado crank/no-start problem by showing all the myriads of ground directions that would have been impossible for me to trace. I can't imagine what madness drove you to stripping down the entire engine compartment wiring harnesses but thanks for doing it, this was a truly meaningful documentary. Best regards to you.
Absolutely awesome video!!! I loved it because I needed to know where certain wires/ground wires were for my vehecle and u showed me without charging hundreds of dollars that A single mother like me doesn't have! God bless you!!
Extremely detailed I'm a wiring guy from stereos to police car up fitting with schematics for led lights, sirens arbortrator camera but this is detailed much simpler than schematics. He didn't have to do this. Much appreciated sir.
Appreciate you doing this, very helpful for my issues, wasn't getting anywhere going thru endless wiring diagrams/ schematics, talk about taking one for the team, lots of work on your behalf , u the man thnks again
The ground wire that goes bad is below the driver side exhaust manifold. Just grab the wire and pull on it and when it breaks you need to crimp a new end on it.
Sir, you are amazing you spend so much time for this video and detailing. I really appreciate it. This is crazy. Thank you so much for this video and God bless you. I’m definitely gonna put a like and subscribe 👍👍👍👍
Thank you! Helped me a lot found the faulty ground wire behind thr motor diver side. Every time I moved the harness pretending to be a bump on the road my engine would go low power track control and brake light on. Rewired that faulty ground wire and now I have no problems thanks!
Oooh yeah that's it this one connects to this one here that connects with that one there that connects with the other one there that connects with the one everyone been talking about going bad back around the other one ... Got it 👍👍👍👍 never could've done it without you THANKS!!
This is a very useful overview of the gm vortec wiring harness and it's potential faults due to particular wire failures. thank you. this could help aid many specific truck conditions, and implies logical ways to fix those issues.
I cut all those splice packs out and used regular butt crimps , solved most problems, on the back of the motor drivers side that harness tends to wear through exposing bare wire those control the trans O2 sensor and speed o found those repaired them transmission is smooth as butter
The problem is the problem is the problem Lmao 🤣🤣 God bless your heart bro My goodness, you destroyed your harness. Hopefully by now your not on drugs anymore. Thanks for the entertainment. Love you man.
Thank you so much. I watched the whol video but I was wondering if there are any grounds to the steering sensors or anything to do with the steering position signal? My 2007 avalanche had a code for the steering position signal wnd also for the rollover sensor performance. I got an alignment done today and the shop only did a reset not a relearn and the steering shows uncentered. I replace the boot at the bottom of the steering column and think i messed something up but dony know what..
I am having an issue with Service 4 Wheel Dr.....2004 Avalanche... ..Once reset it works until a Hard Bump is hit and light error comes back on not allowing the 4 wheel transfer to shift....
I had to take the shark fin antena ,because I got a luxury model , I was getting hacked every time I drove around , the truck would go into reduce power mode , I cut that thing off and it's been good ever cents
Hi there I recently bought me a new radio and I'm getting power from my firewall harness but the radio is not coming on brand new fuses wires hooked up correctly. But when I connect my multimeter tester to it. My wires gets really HOT.
I have a 06 suburban LT I believe a ground for something that causes misfire is bad cause it misfires bad I already replaced all plugs, wires, coil packs, fuel pump and fuel injectors can't find the issue
I have a 2008 trail blazer same problem. I cut 3 grounds from lower right blk.traced them thru wire loom and ended up with 6 grn wires divided them into two sections of three put eyelets on them and grounded them to the alternator bracket.
i have the 05 avalanche and have lost my ground to the ac circuit, do you think its a bad pcm i cannot get ground to my coil of the compressor relay. ive replaced the relay, and im able to jump it and activate the clutch. i also have replaced the contol in the dash and bypassed the pressure switches to check them. seems i just cant get ground to the coil of the ac relay to energize it.
Have an issue battery gauge overcharge to 19-21 voltage. Changed battery and alternator it fixed. Regulated itself let car sitting 4 days before driving it. Turned it on and it was showing 17 on gauge. Pulled it into garage and turned it off and on then regulated again back to 14.5v let it sit overnight and no problem. Took it out tonight and turned off gauge didn't reset stayed at 14v when off turned it on and now it's a 19v radio didn't turn on but was super hot any idea of bad ground possibly?
Only ppl mad here are mechanics for giving up the source of all problems; the ground wires... Lmao . he cant help you get into these hard to reach spots that "stealers" installed them at... Great job. I know exactly where i need to go... He made an error and corrected it in his next video(thanks again!).
great video! My car will no start no crank after a short, if I get out and wiggle the negative battery cable hookup it will reconnect and start again usually, does this indicate where I likely have a bad ground at?
David- I have a real challenge wanted to see if you can help. I have a 2004 Chevy Avalanche and when I go to turn it over all I get is the clicking. Long story short I replaced the starter, did work. I then replaced my still under warranty battery still didn't work. I thought it may be starter relay but didn't work. I then checked my battery with multimeter while it was running to make sure the alternator was charging. I only got 12.6 volts max. So decided to replace the alternator but it is still not charging my battery and truck won't crank without my jump box. Please help!!!
I would first check the main ground to the engine block and the main positive at the starter had seen both go bad at those points.make sure all connections are clean and tight
I have 07 envoy Denali with 5.3 the ac stopped working, rad cooling fan runs on high, no traction control. Loss of communication code to bcm but no warning lights. Gonna assume its a bad ground some place, just not sure where to look or how to fix. Anybody offer some insight?? Can engage ac clutch without vehicle running by hooking 12v directly from battery.
My '05 Burban 2500 goes into low power mode. Left headlight was dim while it was idling. I unplugged the headlight and that killed the engine! Messed my brain up...now it cranks, but no start. And I have to wait 2 mins before it will crank again! Grrrrr.
For some reason unclear to me but I was chasing brake, transfer case, window motors issues. Once I put that ground on my voltage doesn't go down to 13v when I use my windows full.
None of my grounds seem bad. I keep getting a random misfire. it gets bad enough the check engine light comes on. Starting to wonder if I just need new coil packs.
I found the ground to firewall broken today but only problem I have is fuel gauge quit working and it’s not holding fuel pressure once key is off to engine…I also have high circuit check engine light P0463. I’ve been trying to diagnose fuel for a bit now with work kids and also trying I fix my 96 Sierra this just said hi today what are the chances? I know this a avalanche myn is 11 sierra 5.3
If you're loosing fuel pressure after ignition is off it's not an electrical it's a fuel system problem...mine when switch off fuel pressure dropped like a rock and would restart hard and smoke....turned out diaphragm in fuel pressure regulator was busted and dumping fuel through vacuum hose to intake manifold...how do you check?...pull intake manifold end of vacuum hose going to fuel pressure regulator and sucknon it. If you taste gas then diaphragm is broken and fuel is going thru where it's not supposed to....replace fuel pressure regulator
Did he ever show the real ground wire on the right hand side at the back of the engine . That 1 in the back of the right head is a one that breaks and gives all the problems
So basically what your saying is.... That one there goes to there, this one here goes to that one over there, that other one is also a ground that goes to there, these three here go to there, on the other side there are two that go here, and one that goes back behind there and another one that follows the other one to there also... 😆
Just to many things to go wrong no wonder these gm vehicles have so many electrical and sensor problems.. Northern cars must break from corrosion constantly.
You Can See Who Listen To Comprehend And Who Listen To Just React Ctfu He Told You Where Every Ground Was And What Its For . All You Had To Do Is Pay Attention Fseee
The thumbs down come from those who realize that altho he went thru all this trouble to do this, it was completely unecessary. Absolutely no need to tare ALL wires open like that.... if you know what you're doing you can do so without all that mess.

Incredible work! How could these DOPES give a thumbs down??? I don’t know of ANYONE that would go remotely to this extreme. Thank You!
That you hoped it help ...i guess its to much for the haters to understand
The ground wire that goes bad is below the driver side exhaust manifold. Just grab the wire and pull on it and when it breaks you need to crimp a new end on it.
Thanks checking into it
Thank you sir, this video is actually priceless to some who needed this information. 👍 I appreciate that.
You deserve a thumbs up brother!
Sir, you are amazing you spend so much time for this video and detailing. I really appreciate it. This is crazy. Thank you so much for this video and God bless you. I’m definitely gonna put a like and subscribe 👍👍👍👍
Very impressive the amount of time you put into that Video. You must be a very patient man.
Dude you’re the best for doing this and with patience
Thank you! Helped me a lot found the faulty ground wire behind thr motor diver side. Every time I moved the harness pretending to be a bump on the road my engine would go low power track control and brake light on. Rewired that faulty ground wire and now I have no problems thanks!

Make a video
Salvador Ramos was it on the engine block is it better too go underneath the truck
Oooh yeah that's it this one connects to this one here that connects with that one there that connects with the other one there that connects with the one everyone been talking about going bad back around the other one ... Got it 👍👍👍👍 never could've done it without you THANKS!!
🤣Meth is a terrible thing
Exactly what I was thinking.
@@rickc1124 don't think meth heads can spend this much time focusing on 1 thing.
He didn't read it out to you but he gave you the knowledge you may need to figure it out. He saved me about 6 hours of pulling wireloom.
I'm still gonna pull loom but now I know where to unwrap🤷🏾♂️
awesome job,lot of work on your part.!!!
This is a very useful overview of the gm vortec wiring harness and it's potential faults due to particular wire failures. thank you. this could help aid many specific truck conditions, and implies logical ways to fix those issues.
Very detailed and simple for me to understand. Thank u for this video!
The 44 dislikes are from carborater people. 😂
You my friend are a true legend
I have had a bad ground on my gmc sierra 4.8L it was in the back of the block. Thanks General motors for the bad ground wire.
Ty for making this video 😊
Thanks for the detail video .
I cut all those splice packs out and used regular butt crimps , solved most problems, on the back of the motor drivers side that harness tends to wear through exposing bare wire those control the trans O2 sensor and speed o found those repaired them transmission is smooth as butter
What you're calling the injector harness is actually the coil harness. The coils ground on the block behind the P/S pump
And if you watch part 2 i correct myself
Awesome video! Thanks man! 👍
The problem is the problem is the problem
Lmao 🤣🤣
God bless your heart bro
My goodness, you destroyed your harness. Hopefully by now your not on drugs anymore. Thanks for the entertainment. Love you man.
Awesome video
Wow that is a great tool 🔧
I owe you lunch Sr Thank you

your negitive battery cable has sulfided replace it this could be your problem ?

Check the main ground on the block and at battery

Looks like a bad spaghetti dinner
Put your hood to chassis ground it's so important!!!
For some reason unclear to me but I was chasing brake, transfer case, window motors issues. Once I put that ground on my voltage doesn't go down to 13v when I use my windows full.
Does anyone know where the ground for headlights is?
None of my grounds seem bad. I keep getting a random misfire. it gets bad enough the check engine light comes on. Starting to wonder if I just need new coil packs.
I thought the same but I took them off and the surface that makes contact was no good
I found the ground to firewall broken today but only problem I have is fuel gauge quit working and it’s not holding fuel pressure once key is off to engine…I also have high circuit check engine light P0463.

Where does the MAP ground go to? Maybe i missed it
Test don’t guess! I guess he decided to reinvent a wiring diagram and voltage drop testing!
And which one goes to pcm
Now THIS...... This one here. This one right here. See this? That one goes here. Right here. See? See that wire here? And THAT goes there
Too funny
You’re wrong. THIS goes there. THAT goes here. WHO’S on first🤣
Nope. If you look carefully, this one goes here then goes there into here and into there.
What was the problem with your truck?
I have a 04 avalanche abs and battery light comes on all window lock control not working i got a good battery any help
First test alternater and body ground coming of battery
Did he ever show the real ground wire on the right hand side at the back of the engine . That 1 in the back of the right head is a one that breaks and gives all the problems
Right around 4:50
So all 4 passenger coils are not working on my 99 Sierra 5.3 would it be a ground from the pcm
Yes. You can jump a ground to the black wire of the coil plug. (Rectangle white plug) and should come on. Its very common
@@johnsonbobo2376 thank you sir
6 seconds in the video and I'm scared😆
😂😂😂😂
I want to complain but I’ve got 242,000 trouble free miles on it until now 🤣 I guess it’s my turn!
So basically what your saying is.... That one there goes to there, this one here goes to that one over there, that other one is also a ground that goes to there, these three here go to there, on the other side there are two that go here, and one that goes back behind there and another one that follows the other one to there also... 😆
No no no don't do that what did you do I think 🤔 that GM truck will never ever be right after that ?
Just to many things to go wrong no wonder these gm vehicles have so many electrical and sensor problems.. Northern cars must break from corrosion constantly.
You Can See Who Listen To Comprehend And Who Listen To Just React Ctfu He Told You Where Every Ground Was And What Its For . All You Had To Do Is Pay Attention Fseee
A 5-minute video turned into 30 minutes
I think u lost your mind
Yeah
He lost something lol
Looks to me like it’s time for a whole new harness....
Ls5.3 mother wireing
So did you sove some sort of a problem or waste 20 minutes of my life?
Just trash the truck. I having same issues
The thumbs down come from those who realize that altho he went thru all this trouble to do this, it was completely unecessary. Absolutely no need to tare ALL wires open like that.... if you know what you're doing you can do so without all that mess.
F
I have never heard someone talk so much and say nothing at all.
you should not be working on cars, trucks, or electrical.
