Even on the '8, some ground wires are white and still others are black AND red!

I don't know. Resistance isn't everything. Current load is he other part of the equation. That said, it might work OK.

The black one in mine. The yellow is Richard Paul's (AxialFlow).

Dielectric does NOT mean conductive. It means non-conductive, which dielectric grease is.

It is non-conductive, but when you slide the connectors together there is metal-to-metal contact and the grease gets displaced but the area around connector is protected from moisture.

I wouldnt use it on a ring terminal, like a ground wire however.

Jeff, just to be clear, the circle plate up top is zinc? I figured it would be aluminum, or is it zinc coated?

That is why it should be used sparingly when installing plug wires, right?

Nah. Glop it on. It only remains in the areas where there is no metal-to-metal contact.

I changed my DIY grounding kit to mimic Jeff's kit (no more daisy chain) everything directed connected to the negative battery terminal, it might be that the ECU is still ajusting after resetting, but it seems to be running rougher at the moment, especially under deceleration. I think it needs a few drive cycles to settle in.

I've got a direct ground for the alternator, engine, coils and chasis.

Curious how you did the coil grounds

when you look down by the coils, there is a stock plastic shielded tube part of the wiring harness running through it that is connected the coil plate to hold the tube in place. Since it didn't seem to serve an important function, I removed the plastic clip that held the wires to that point on the plate, and used the hole drilled in the plate where the plastic clip was to attach a ground wire with a screw and a nut.

I think MM did the same thing as well. the tube with wires is covering the spot in his pic, so you'd have to dig down there to see what Im talking about.

I get a pic tomorrow.

There is an "accessory bracket" for want of a better name on the top of the engine...under the intake manifold at the back of the engine. This is used for a grounding plate for a number of harnesses. I think it is important to ground this back to the battery. There is a bolt near the oil filter..towards the top of the engine that is easy to access to ground this. The coils and the condenser are grounded to this.

I grounded the "B" wires of my coils back to the battery a few days ago as well. A well respected meber of the racing community has said that their coil failures stopped after they began to add extra grounding to the coils. All I can say about this is it seems to have made the idle so much smoother, and I seem to have lost a mid-high range hesitation that I had.

That must be the one that is easier to reach from under the car right?

Under the spark plugs?

Look behind the oil filter from the drivers side, and a bit forward...you will see a 10mm bolt with some ground wires on it...... thats the plate I was talking about...It is on the top of the engine behind the intake manifold

We just got it done, it does seem to give better engine response, and does feel more powerful...

Pics attached, Buddy Club grouding kit with condensers.

Peformance wise, they would do nothing. The ground would reduce EMI, but I don't think that is a problem. If the plastic/silicon cover over the sparkplug wire ever broke down, it would have a very short path to ground and possibly burn up one of the coils.

Have done a complete grounding kit to my 20B-REW powered Cosmo. Made it myself for around $20. being an electronics tech helps in this case.

Same results. Started easier, idled smoother, reved cleaner etc. Better top end

Very worthy modification

can someone please post the grounding spots for the coils & throttle body??
a DIY would be nice on these spots being that they're not usually grounded w/ the majority of the available kits out there...

Here is a pic I pulled from the Oil change DIY

By the intake manifold next to the oil filter... close to the green and white vacuum check valve there is a metal plate with wires attached that is where the coil packs ground to.

The coil packs ground to the engine (which is grounded to the chassis), not those 2 tiny wires. Something else in the engine bay is using the metal plate for the coil pack as a ground, thats why they are attached.

BTW, that Buddy Club ground kit is out of control. As a rule, grounds should be as short as possible. Plus, the longer the wire, the more resistance it will give = not good.
