The question is what you're trying to do with your TBI swap - i.e what engine are you trying to EFI (350/454) and trany?

IRC HD 454 calibrations were used on on 3/4 and 1 ton trucks.

The 454 TBI system is from a 92 1 ton with 4l80e. I'm putting it in my 76 4x4 crew cab with stock 454 and NV4500. I think I've elemintated the wiring specific to automatic transmission control.
What it the function or purpose of the red/white wire coming out of the FP relay? It's labeled "fuel pump prime" and diagrams show it terminating at what I assume is supposed to be a plug connector. This wire was ran into a connector that contained the auto trans wires, and I couldn't find a diagram for that connection. Other than that, I think everything is looking good.
