PO of my car ('73 w/D-jet) had installed carbs and had the fuel pump under the gas tank. The FP was wired directly to the #8 fuse on the panel, and the ground attached at some point above the fuse panel I believe. Anyway I want to go back to having the FP run through the relay on the board in the engine compartment since I'll be using fuel injection. So I disconnected the wire going to #8 fuse (+ FP wire) and made a connecting wire to the Black/Red wire at the front right hand side of the engine compartment which was originally used for the FP. This didn't work to energize the FP at all, nothing when I turned the key and I'm not sure why. Can anyone tell me what I'm missing? There is a FP relay in the board that I believe is good.

Clay - I will take those measurements this evening. But just confused on the whole harness thing. I mean I do have new ground wires going to the back of the alt (D-). Basically with what you're talking about building won't require removing the complete Intake/CIS unit AGAIN will it? I feel like I've done that more than I care to remember and I've drawn up a schematic and taken good notes of what everything in the wiring harness goes to. So, is the new harness just to controll the FP and relay? Oh, and no I haven't been able to get the engine started any more than it did the other day, which was a few seconds. Please pencil me in for Saturday help if you don't mind - I owe you big time!
