Anybody know what color the fuel pump trigger wire is under the backseat at the bulkhead? Thanks! 2000 Z28

Bringing this one back. How would the trigger wire go all the way back if the relay is in the kick panel?

In the strictest sense, it doesn't. The term trigger wire relates to the relay, which is up front. However, if I were to put an aftermarket fuel pump on, I would use the power wire from the original relay to the pump as the trigger wire for my new relay. (I would install a new wiring harness to handle the increased current demand.) Hence, the original power wire to the pump becomes the trigger wire to the new relay for the aftermarket pump.
Hope that makes sense.
