Grounding Locations?

[Skoobie]

Well I finally got off my lazy ass and upgraded my ground after the 3G install (1 1/2 years later). I just wanted to know if I chose an acceptible anchor point. I ran the 4g wire from the strut tower to a bolt on the back side of the EGR spacer. Is this sufficient or should I try another spot. Theres also a standard ground strap running from the transmission bell housing to the firewall (that was already there before the 3g install).

Hmmm,the back of the EGR spacer?Wasn`t aware of that location.

Anyways,the best ground source on the block is directly into cast iron,on the block.If yours is on the tb or egr spacer,your going through aluminum...not as good a conductor.

Other locations are the empty 7/16" drilled/tapped hole at the front of the drivers side,(stock) head to driver side sway bar mounting bolts or where the negative battery cable goes to the block to the same sway bar bolts.

I was trying to reenforce the ground that usually goes between the upper intake and the firewall. I figured that was close enough

i would ground it to a header-manifold bolt i'm with 8950HO thinking about the alluminum being questionable the header-manifold bolt to block no question there...

I thought about it but I was worried about the heat issue. Its just a 4g wire from home depot. Wouldnt the wire casing melt?

they sell a heat wrap at all local parts store and when i grounded mine i used 1 factory bolt that had the protruding stud past the nut where i placed the ground wire and nut to secure and you can position wire where the heat won't affect it as you would the plug wires...goodluck.. and you can even cut insulation away to prevent melting without any problems...

FWIW, I added an additional ground on my '94 from the frame rail to the underside of the motor (motor mount, on the motor side) and even in that relatively crappy location, it helped stabilize things.

I think simply grounding the motor is the most important thing - where exactly the ground is, is not as important as simply having the cable.

One can do garage testing with a jumper cable to see if anything improves with changing the location of a given grounding spot.

Jumper cable....good idea. Thanks hissin
