When I took the engine out of my 1980 FI engine many moons a go I never thought of taking pictures of the wire harness ground wire location.the only one I know of that I see is the transmission to the chassis.if anyone can take a few pictures of the ground wire in the engine bay where they go to and go from should be much appreciate.I also recall a wire on the engine mount but not sure.

On mirafiori.com, there are some factory manuals that explain all this. You have to register to access the site. Or maybe someone on this forum remembers.

Thank you but I have the factory schematic of electrical but it doesn’t show me exactly where the bolt to that’s why I would like some pictures so I can keep the car electrical to original location as possible during this restoration of the vehicle

there are some factory manuals that explain all this.

I don't have any photos but the Fiat publications Bryan is referencing do have some photos and very good descriptions of where all the fiat grounds are located. I personally use Fiat publication: Spider 2000 Electrical Diagnostic Manual 1980-1981, as my go to reference for most electrical questions and issues.
