firewall ground
 
Alright, this is driving me crazy. I've been looking for the firewall ground (from the grounding guide in the archive), the one that you ground the trailing coil to, and can't find it. I look at the picture and can't find where it is in the engine. Help, please?

Trailing coil does not ground through the firewall.
The trailing coil actually grounds through it's metal bracket.
There is a capacitor that damps the switching noise from the toggle function, but this is not connected to the firewall either - this capacitor is grounded on the backside of the driver's side strut tower.

I mean the firewall ground that is used for the new additional ground.

I think you've been misreading the FAQ. As Ted said the coils ground to the chassic throough their brackets, so IMO "grounding" them is pointless.

There is a thin ground wire on the firewall that connects to the back of the engine (it's the only one, hard to miss). I simply added another 8GA wire in parallel with it. I saw no need to actually remove the original wire.

Yup, got that wire you're talking about. I guess it does sound kind of pointless to ground the coils. Guess even archives aren't infallible.
