ive been going through my wiring harness, which was pretty hacked by the guy i bought my car off of, just trying to fix it up so everything is where its supposed to be and getting rid of the excess. i have an obd2a to obd1 conversion harness and im running a jdm obd1 p72. currently im trying to figure out where pin a27 is supposed to go? right now there isnt even a pin in there. from what ive read its supposed to pick up a signal from the rad fan at some point and artificially raise the rpms of the motor when the fan is going to kick on so that the motor doesnt bog. but i can't for the life of me find a wiring diagram including that pin. anyone know?
