I admit that I am out of my league when it comes to electical wiring, theory, and reading diagrams, so I have a question....
I am going thru the wiring on my 75 L-jet. I replaced the OEM fuse box and just kinda kept going. I towed this car home 18 months ago, so I have no idea what works and what does not. Anyway, I see a heavier gauge wire in the gas tank area (tank is out). The wire is Black with a Red stripe. I followed it back to the relay board and figured it has something to do with the fuel pump. The color diagram on PP leads me to the FP relay and then on to a white wire labeled 12. The PO has the fuel pump wired directly to the coil with a heavy red wire that I know was not OEM. And this mystery BLK/RED wire is cut on the Fuel Pump end. Any ideas why the PO did this? Will I need a new relay, maybe? Thoughts anyone? Thanks, Clark |

This wire had been cut. it had no connector. Car is a 75 1.8 with L-jet and the pump is under the tank. All the FI stuff was installed when I got the car, so no evidence of carbs. Not sure about the DUAL RELAY tho. I don't see that mentioned in the Haynes book either.
