I'm in the process of completely wiring my 84 SVO. I have some questions now and also plan to just come back to this thread when new questions pop up. Unfortunately, I don't have a factory wiring diagram. What I do have is a Ron Francis EFI harness and chassis harness. I still plan on tying into as little of the old wiring as possible.
First up: fuel tank. I switched my fuel system out to a single in-tank pump. I would like to tie in where the wiring comes in through the trunk floor. There are 4 wires: pink, which should be power to the fuel pump, 2 black wires (I'm going to cut out the resistor wire), and a yellow wire (fuel gauge?)
i already have the relay sorted out, so I'll tie that to the pink wire. Any recommendations on the grounds? Is the small black wire paired with the fuel level sending unit wire?
I'd really like to avoid dropping the tank again. Thanks for any help.
