Hello
I have a 1989 240SX (KA24E) and i am currently do an engine swap from a 1997 S14 SR20DET. I have a few issues that need to be addressed.

1. Oil Pressure sensor 2 pin vs 1 pin
The current oil sensor on the SR20 is a 2 pin. The sensor on the KA is 1 Pin. I am reusing the lower KA harness. I cant seam to pull off the SR20 oil sensor, without breaking it. So i have 2 choices a) break the sr20 oil sensor and then plug in the ka sensor. b) wire up the sr20 2 pin sensor.
I really want to do plan b) but i dont know what the 2 pins are connected to. i have deloomed the SR lower haness and cant seem to figure it out.
Question 1: How do i wire up the 2 pin oil sensor? It one just connected to the ecu and the other ground?
2 Pin SR20

1 pin ka24

i wired in the single pin from the KA. only wire i used was the yellow with green strip and the other got grounded to the frame. i can have pics later on today when im off work.

That SR sensor looks just like a Z32 oil pressure sender that is used for the OEM oil pressure gauge.

To get that sensor off the SR you will need a 17mm wrench at the base of the sensor (under all that big metal mass).

On my sensor I only have a single signal wire from the harness running to the gauge.

s13bdafocker is would be nice if you could send my a pic.

So i can wire the 2 pin oil sensor by connecting one to the ka harness and the other to ground?
