Picked up a 76 out of texas that had been converted to single carb that just doesn't run very well. I decided to convert back to original FI, essentially everything is gone and I am working on understanding the system. I guess my first question is where does the fuel pump draw power from? there is a single black wire underneath the fuel tank that has no power to it but all the relays have been removed and Im waiting on those from pelican

For smog purposes CA-only model 1975-76 914s also had a 'Fuel Cutoff on Deceleration' system which consisted of a 'Speed Limiter box' (its a computer not a relay), and it plugs into the FI harness. It works in conjunction with a 1975-76 ECU and monitors speed characteristics at the FI trigger points, deciding when to stop fuel. I make that FI harness if needed. SL box image below, it lives just below the battery area in the engine bay had has a dedicated branch on the wiring harness with a 6-pole connector.
