I just recently picked up a 77 hilux but the harness has been cut in multiple different places, ive been look through different wiring diagrams and cant figure out what color the wires are that run to the positive terminal on the battery can any body help me? Im trying to atleast get the lights to work as it currently doesnt have an engine in it the girl i had bought from had stuffed a ls 5.3 into it but took it back out shortly before i bought it
