Help anybody know where the gray wire goes from the + side of the coil? I'm not getting to it and I don't want to tear the wiring harness apart to find it. I put a new ignition switch on the column and a new fuel pump relay in it. It doesn't get power to the fuel pump. The truck sat for 13 years. I ran a jumper wire from the batt. To the coil and put gas in it and drove it home. But can't figure out why I don't get power to the fuel pump without the jumper wire. And I ck. All the fuseable links and there all good so are all the fuse's. I'm at at lose as where to go next.
