Sup guys....

I just finished working on my friends car... the car is an 86.5 n/a auto, and we dropped an '88 turbo 5spd in there, along with the turbo harness and ecu.

I'm getting a code 32 (something afm) and a code 52 (knock sensor). The thing with the knock sensors, is that the old owner had re-wired the KS and had wires coming straight from the sensor to the ecu. The other thing is, I don't know if he had them reversed or not... ie KS#1 to ecu KS#2 and KS#2 to ecu KS#1.

What do I do guys???

btw, I've checked the wires, and made sure they were connected to the sensors. And one more thing, the tach doesn't work, but if I put a turbo tach in there, it should right?

the AFM might actually be damaged. its very easy to hurt the electronics if it gets dropped on the ground or kicked or bumped on a hard surface. its basically comprised of a laser and a mirror, so if it gets out of whack, its not going to work right,justl ike when you bump a CD player from 1989.

also, you can use a multimeter to test the continuity between the KS1 and KS2 pins of the ECU harness and the knock sensor plugs n the engine bay. you may need a helper for this though.

if the knock sensor wires are fuxked up... pick up 6' of USB 2.0 cable. there are 4 conductors in there. you can twist them into paires on either end. just keep the colors straight and you can use that to rewuire your knock sensors.
