For Plastic Intake Manifolds - Bolt the ring terminal meant for the top of the intake manifold to the TGV block where the current ground terminal touches the intake manifold.
Can i ask where the tgv is on a 05 Outback 3.0 LL Bean(also plastic intake manifold)? I'm redoing my grounds with bigger/better wiring & I can only find the one to the driver strut, one on the passenger side fender(tiny one that goes into fender by power steering reservoir) & the one going to starter. I do see two under throttle body, on top of motor, two side by side. But those do not go directly to battery. I cannot get a straight answer from anyone. I'm running from behind alternator(just like in video except mine is on the bottom right instead of top right) to battery, from batt to strut, batt to starter. Should I run to one of the ones(two side by side) on the block as well? I really appreciate it. You guys really are a big help. Thank you!
I have a 2014 WRX, I think I have a grounding issue as my radio flashes when I have my turn signal on but only intermittently. I want to install this kit but I’m having a hard time finding the last ground connection. I know you say it’s on the TGV block but I’m still not finding it.
I ordered this kit from the UK and it was delivered within 5 days. Have just installed and it has fixed my accelerator hesitation issues, what a relief! Thanks iWire
i set up the this ground kit as you instructed and is amazing how the car feel a bit torquish and with more power , even the head lights are having more volume on brightness,
For those wondering this works well on the fa 20 make sure you run all the grounds before you secure it I almost didn’t get the alternator thank you I wire for a great product !
I've been having some weird issues with my '04 Baja NA 5spd, namely flickering lights (interior and exterior) and annoying surging while coasting. Replaced the alternator with a Denso unit and that ultimately didn't solve the problem...I've been told to only use OE alternators, but I have a feeling it's a ground issue. When I dig the car out of winter storage I will give the grounding kit a try. Thanks!
@@Tanya_Von-Degurechaff yes...one of the harness eyelets bolted to the position battery terminal was just loose 🤦 found that out before ordering the kit
@@LoveMyZJ thats crazy, such a small thing too, you wouldn't know it. My car is having some weird issues too, the ac comp pulley and waste gate actuator solenoid and fuel pump, all keep cycling with the car off and key on the on position, super annoying.
i have a loose wire on my main cable I could not figure out where it came from on my 2012 subaru legacy looks like it could be from where you just attached your grounding kit
Hi, there. I just ordered the grounding wire. I watched your video on installation, and I am having a hard time with the alternator wiring, I cannot seem to remove the bolt as it seems it may be stripped. Any ideas or suggestions? Also, the wiring for the engine block, has large bolts, so I am looking for more ideal spot. What other spots could you suggest. I have a 2016 Subaru Forester. Any advice is sincerely appreciated. BTW, Great packaging and the thank you notes are a first class touch!
We appreciate the compliment! Sounds like some sort of bolt removal spray to get things loosened up may be in order. As for the bolt locations, as long as you adhere to the general principles we've described you'll be good to go.
Hey how's it going? I really need some help, I have a '05 Outback 3.0 LL Bean(VIN-4S4BP86C154335722) & out of nowhere my car started bogging down really bad, really rough idle, misfiring etc. Ive cleaned throttle, replaced maf, map, crank, cam sensors, upgraded coils & plugs. It did nothing, had a new tranny put in a month ago, I really think they messed up some grounds. I haven't been able to find locations for my specific car, added bottom ground straps(they weren't there), cleaned the chassis ground, starter and two grounds under air chamber box/throttle body. I have the plastic manifold & cannot find any other grounds, took alternator off & there weren't any grounds. I have plenty of wiring(I'm a car audio guy as well) I just don't know where to look/add or replace. I would greatly appreciate any help. Been @ this for over a week straight now.
You do not want to remove the original grounds. They are still needed for the ECU. This harness brings the ground to the manifold, so those original ground works better.
Yes and no. This kit is designed to primarily improve the electrical efficiency of the ECU and engine-related components. The "big 3" is more related to body equipment like stereo. We talk about this a bit in the post here - iwireusa.com/blogs/iwire-university/grounding-issues-iwire-grounding-kit?_pos=2&_sid=c89234f31&_ss=r
@@iwiresubaruwiringsolutions5538 In this case, it would prevent corrosion and keep the circuit clean. I use it on grounds and high-amp connections. Great for any threaded aluminum, too.
What else would we need to ground if we were adding an aftermarket stereo system and we wanted to do a big 3? I know this kit has some elements of the big 3 but not all. Do you have any plans to make an all-in-one grounding kit that incorporates the Big 3 and the current grounding kit?
We are focusing on ECU/engine-related issues, so it's not likely we will address anything else regarding the Big 3. More about this kit can be found in the link below. iwireusa.com/blogs/iwire-university/grounding-issues-iwire-grounding-kit?_pos=5&_sid=d6aa39b2e&_ss=r
Awesome video thanks a lot , question instead of sandwiching the cable with the alternator bracket can i put the ground cable in front of the beginning of the thread with a nut, don't want take out my Perrin mod cover from the alternator lol, also is there's another option for a spot to put the ground cable that goes on the block engine, can i put it in one the 4 sides of the throttle body? I have a STI 2016 limited
It would be fine to put it on the front part of the bolt instead of the back for the alternator. You'll need to make sure one goes to the long block. The throttle body would be the intake manifold, so you should have another cable that goes to that somewhere.

Lol seems very straightforward and makes sense
As with all solutions without seeing the car, I can't guarantee it would fix your problem. I can tell you that it will eliminate a variable that very likely could be the cause of your problem. Worst case you've made your grounding system work better so your engine will likely run a bit more efficiently and will be able to determine that the root cause of your problem is not due to grounding.
We don't add one to the starter because this grounding is for engine/ECU-related signals. The high current of the starter would not be ideal with the more sensitive electronic components.
You guys are the best - thank you for teaching me about all of this. Installed this kit on my 2007 Hawkeye STI without a hiccup @@iwiresubaruwiringsolutions5538
You can but due to the tendency for the battery terminals to get corroded we do not suggest it. In addition we prefer the extra capacitance that the chassis provides where the negative terminal meets the chassis.
2011 Outback. Every once in a while my dash lights/warning/indicators etc., come on. So I disconnect the battery and clean the terminals. Especially the POSITIVE. Problem solved... However, lately its been doing it more often. Should I track down a Subaru wiring diagram and clean ALL the ground straps and connections on the car?
I have a 2018 Forester 2.5i and I have voltage issues. I replaced the factory battery with an AGM battery. I still have voltage issues. I’m thinking of the big 3 upgrade, till I saw this.
Our Grounding Kit should be all that is needed. Unless you have a large stereo the alternator would not need to be upgraded or changed. More about grounding and the big 3 here - www.iwireservices.com/post/grounding-issues-iwire-grounding-kit
Question but are the ground locations pretty much similar to a NA Subaru? I have a 04 forester and im getting whistling noise on my aftermarket sound system so im looking into doing fixes to my grounds
@@iwiresubaruwiringsolutions5538 true. But the small ground your referring to is a small factory ground? Isn’t the point to make them bigger? Or moot at that point ?
@@daveroski We are not necessarily making them bigger, but more about making sure all points are well grounded. Our kit is designed for ECU and engine efficiency which doesn't require extremely large gauge wire, just the right size wire in the correct locations.
