1984 L69 Oil Pressure Sender and Switch
I have a 1984 Trans Am, formerly an L69 (now a 350 w/ a Holley swap) with the vapor lock recall done (in tank fuel pump and associated wiring). I'm installing after market gauges in the car so I want to use the oil pressure sender they sent me. In pulling apart the oil pressure setup on the back of the motor, I realized there are two sets of wiring harnesses on there, a two prong and a three prong.
I know that the two prong is the oil pressure switch that runs the in tank fuel pump. Does anyone know what the three wire one is? I know one wire is for the gauge but are the other two also a switch of some sort? If anyone has wiring diagrams, that would be tremendous.
Basically, I'm trying to decide if I can get rid of the three wire one and just replace it with the sender that Speedhut sent me, or if I need to run all three.
Also, one of the prongs on the two wire switch broke off, anyone have an idea for a P/N or replacement? I've seen some on Summitt but they have a 50 psi top shut off and that seems low.
