Does anyone have a diagram showing all the ground points io an "83 944? Thanks in advance!

 

Damn typed my response and my browser blew up.

So anyways. It would be easier to disassemble the car and make your own schematic, than sort through the plate of spaghetti that is the manual.

The basics are. Off the battery terminal it goes to a bolt on the forward firewall byt he fan. On the otherside fo the firewall there is a strap that goes to the bell housing.

On the front of the framerails by the headlights are two collection points (1 each side).

My advice is to run another heavy duty cable to the valve cover, and from there two smaller ones to the forward collection points. I also ran one into the cabing and attached it to a screw on the DME and to a grounding point on the instrument panel.

 

There is a ground point in the cargo area, driver side, under the carpet between the tail light and the license plate well.

 

There is also a cluster of grounds behind the instrument cluster. Not sure if you will see it if you remove the instrument bezel. (I'll find that out this winter).

If you move one of the fuse boxes you will see it tucked up in the corner.
