I have an issue with the fuel gauge and oil pressure and low fuel light comes and goes out.
I would like to get a schematic to locate the ground location for those gauges
Thanks for any help with this matter

Here is full elec schematic, but what you really need is Elec and Vac Troubleshooting book.
Thought I had that digital, but can't seem to find it.

The 86 uses a VR for those gauges. I wonder if that’s the problem? One is available from LMR:

Good luck.
