Wires on my car have been cut to the accelerator pedal position sensor and had to get a new connector. I don't know what the 5 wires actually are so how can I connect the connector without knowing the 6-pin wiring diagram.

Hi Ken! I'm not Annette, but I was able to confirm the 5V reference voltage isn't being supplied to circuit 1274. Thank you very much for the information above!
I'm going to try to find where that circuit begins so I can isolate where on the wire I have damage. From what I saw, the unwrapped portion of cable seems to be in good condition between the engine bay connector and the pedal connector, but I'd like to verify continuity with my multimeter. Then it's from there back to whatever supply it gets.
