I thought I would post some pictures of my homemade grounding kit. It cost me about $20.00 or so from Home Depot. I used 4guage stranded wire and some standard crimps ends. I think the job came out pretty well. I haven't ran a cable from the alternator as of yet because it seems like a lot of work at the moment. If you see anything I can approve on, please tell me!

Nice! Did you notice any improvements?

Idle is much smoother and lights are brighter. The car also feels like it responds a bit better than before. Can't go wrong for $20.

I've been considering this for a while now. My car doesn't even have the factory strap to the firewall. I've searched the wiki and can't find the answer I want.

Where do the leads connect? Are those ebay kits ok or should I just fab my own? Anyone on here still make kits? Thanks.

Yeah my car was missing some stock ground wires as well. It's very easy to do. You could knock it out in no time once you have the parts. This is what I did basically. You basically want to daisy chain all the wires back to the negative on the battery.

Negative Terminal to firewall behind brake fluid. (Image 1)


Negative Terminal to Throttle Body. (Image 1 & 2)


Throttle Body to Passenger Strut Tower & Firewall. (Image 3)


Negative Terminal to Starter. (Image 1 & 4)


Starter to Head (Image 4)


ECU to Negative Terminal. (I daisy chained this cable to the starter cable seen in image 1)



So basically you want to have 3 separate cables coming off the negative terminal of the battery. Also, you would run a cable for the alternator to either the Throttle Body or the Passenger Strut Tower. I have yet to do this myself. I hope this makes sense.

Yeah, thanks. That makes sense. I appreciate your time.

Anytime and good luck! Let me know if you need help. I live not to far from you in Bellflower.

nice work! sometimes it's very suprising what a grounding kit can do for a car. awesome for $20!

Tell me about it. Thanks!

ok, so can we say OVERKILL!? I agree that a ground kit is definately a good investment, but DUDE! c'mon now. Why did you ground everything to everything? And why not hide anything? not exctly appealling to the eye. Maybe you know something about it that i dont. so all in all, GOOD JOB, but isnt it a bit much?

Not really. From what I have read anyway :shrug

Actually no it isn't. I'm still missing a wire from the alternator. All parts of the car need to be grounded (daisy-chained) back to the negative point on the battery from what i've read on countless websites. I repeat, all of your ground points need to meet the negative terminal of the battery in some way. As far as hiding the wires, you can do that if it floats your boat but I decided not to and I don't think it looks bad the way I did it.

They do. It's called chassis ground. All modern cars come that way.

Your eclipse is very nice. Keep up the good work!

Thanks. Right now it keeps the garage floor from floating away. Contact DR1665 Driggsy as he made a really comprehensive grounding kit and instructions a couple years back. He has good pics and good stats on it.

That's what I'm after is the instruction. I didn't see it in the wiki. Guess I'll have to dig deeper. I'm going with one of the 8ga. ebay universal ones. Shipped for under $25.

You may want to go bigger than 8ga...

8ga for $25 or 4ga for $20?

Don't buy an ebay kit. the wire quality is shitacular. most brittle junk with insulation that will melt the first time you rev over 3k rpms and it's too close to something warm. luckily I wasn't the one to discover this.

the Home Depot 4ga wire is much better quality and for ~$20 you really can't go wrong.

if you really want something that will pass a LOT of current and look good go buy some audio grade 4ga from a stereo shop. monster is the best but even some of the others will work great. expect to pay a little more if you go that route.

for the best performance remember to rewire the positive lead from the alternator to the battery with the same size wire. your circuit is only as strong as the smallest wire in the system. the 8ga wire that our alternators are wired with from the factory is not up to the job.

Hey, Nissh could you tell me what parts to buy I would like to replace mine. I now have room in my garage to do it..

I have a copy of Driggs grounding diagram its very simple, it's also in the wiki pics.. I can post it but would take a few mins

How would I replace my positve cable, I do have the factory alarm and I think its on the positive side.

Go to electrical area in Home Depot and ask one of the associates to cut you (# of feet) 4guage stranded wire. Also in that section, you will find the 4guage wire crimp ons as well. I grabbed a lot of those just to be on the save side and I always like to have spares. As far as the positive cable, I have yet to do this myself. Once I have some extra time to run the ground cable from the alternator, I will also run the positive cable. Unfortunately I cannot tell you how to do that part because this will be my first time also. Good luck. Before I forget, make sure you clean the ground points very will before you attach the wire.

hello, i am new to this site, i have built my mother a 2gnt and i also used a home made grounding kit, but one thing that i found through voltage testing is one thing to also do, our ground wire to the starter from the battery. if you look, what are the two peices that the ground wire is bolted to, an aluminum case of your tranny, and a aluminum starter, what when it comes to metals is one of the least conductive, move the ground from the starter bolt to the next bolt up, where it bolts through the block ear, moving it on my mothers yealded a 33amp reduction upon starting and it boosted constant idleing voltage .4 volts, i will take pics and post on here of my exact setup.

Interesting, post it up

you will have to give me a few to figure out how to get the pics on here, ill go take them rite now, excuse the dirty engine bay, havnt had the time lately to clean moms car, been building my 91 and workin way too much, i might need help getting pics on here, if needed can you assist?

Definitely!

mail me exactly how to do it on DSMking91@aol.com. i have many pics to post and exactly the way i was told to use the grounding kit correctly, i just happened to figure out the negitive battery cable idea one day when i was replaceing the starter wire and ground wire, it was sheer curiousity that led me to test the amp draw n voltage before and after i moved it

I'm posting these pictures for MoMs2gNt.

the way i was told to properly use a grounding kit is to return all peices of metal that has a sensor attached to it that has a gasket seperateing it from another peice of metal with a sensor back to the battery... i have grounded the TB once, the intake once and then led one from there to the firewall, one from the thermostat housing, two from the head, one from the bolt that bolts the ECU to the bracket, that way the bolt is going directly into the ECU, and then the one from the battery to the strut tower, i also upgraded the crappy battery terminals and the power and ground wire to stinger pro series 4gauge stereo power wire, i noticed a difference in the way the car idled, the HIDs seemed to be a bit more crisp, but i did notice that the guage lights seemed brighter, it might have been my imagineation but i thought i noticed a difference on the top end pull, could be wrong though.
