1994 GMC truck unknown plug
I have a 1994 GMC Sierra with the 5.7 (350) engine that I bought three months ago. On the passenger side of the engine is a plug with two wires, one wire is brown the other is blue. I can't find a place to plug this wire in. It is near the EGR valve but the EGR valve does not have an electrical connection. The EGR solenoid has a connection plugged in. The truck has an automatic transmission and AC.
Does anyone know what the purpose of this plug is?
