noob first swap need to know what these are and where the get hooked up or do i need to run wires for them car is 92 bubble motor is b16a
The bottom picture is the oil pressure sending unit. There is two wires that run to it, with a black boot that covers it. I don't know a lot about EG swaps, so I can tell you what wires to run. The top picture is the coolant temp. sensor, if it's on the passenger side of the head (can't tell in the pic).
what he said.... you don't have a plugs on the engine harness looking for a home? The ECT senor should have a red/wht and a grn/wht wire running to it. I can't find what color the wires for the oil pressure unit are supposed to be. If no one else pipes in, I'll look at the motor in my garage tomrrow and let you know.
