so i changed the harness on my tt, the problem is that the new(to me) harness doesnt have the egr temperature sensor plug, and im gettin a code 35, ive looked at some threads and found that on the ecu(itself) slot 30(this is where the black wire goes) and 39(this is where the orange/ black line wire goes) are for the sensor, but theres alreay a wire on 39(white wire, dont know what is for), my car is a 91, the harness is for a 93, i thought they were compatible, do i have to de-pin and rearrange the wires, any info would help a lot, thanx

 

figured it out, i think the guy who sold me the harness de-pin it to remove it, and when he re-pin it he put it in the tps input in the slot for the egr temp sensor, thats why i didnt have a slot for the resistor on my ecu plug, so now i have to move the tps wire to its correct location and put the resistor on the correct slot

 

Hope it works out.
