Ground connection locations

[Christien]

I know it's been discussed here several times, but after many searches I couldn't find any definitive, clear answers.

Does anyone know the exact location of all the ground connections? I've learned that there are 10 in total - apparently 4 along the firewall, 2 more somewhere forward of there, 2 behind the headlights and 2 in the hatch along the rear wall. I've also heard of one from the starter to the bell housing. I've been able to find 2 along along the firewall (one from the negative battery terminal and one about a foot towards the driver's side), the 2 behind the headlights and one in the back hatch area, but that's it. How the hell do you access the bell housing with a bloody hoist? I had the car up as high as I could get it on the jack/jackstands and couldn't come anywhere near getting my hands and arms up where they needed to get.

Thanks!

I can tell you where three are...

One right on the back of the engine.
One right in the battery compartment on the body.
One under the dashboard near your steering column.

There are two behind the oil filler cap. One is a larger ground on the engine and the other is smaller and is on the bell housing. Depending on the routing of the wiring harness, you may or may not be able to access them. Much easier if the intake manifold is removed, but you may not want to go there. I think that there is another one above the hood release lever in the footwell near the cruise control computer. Porsche includes a graphic locating them on the wiring diagrams. Check this site and Clarks-garage for copies of the wiring diagrams.

This might help you it is out of the Haynes Manual.

Its the very first page of the electrical diagrams in the back of the book.
