Wiring Fuel Pump Relay to Grn/Wht Wire. Wire is always hot Hey all,
I'm finishing up my harness modifications for my LQ9 BMW E36 swap. There's one thing i can't seem to figure out. I've looked at the pinouts a million times. I'm using the green with white stripe wire from Pin 9 of the red connector. I've looked at my bin, and i believe it's set to 30 seconds fuel pump run time before start (which seems REALLY long, but it's a totally stock file untouched aside from VATS removal). The fuel pump relay control wire stays hot. It never shuts off after 2 seconds, 30 seconds, or any amount of seconds.
Any ideas? IDK why this would matter, but some of the sensors aren't plugged in at the moment (crank position sensor is the only one i could possibly imagine that could affect this as maybe the PCM thinks the car is running?)
Input is greatly appreciated!

That would make sense. I'm waitin on the correct tac module so that could be the issue. I plugged in a spare pcm I had which just so happens to be DBC and it primed perfectly for 2 seconds. I'll follow up once I get the TAC module hooked up.
