Ok its a S4 turbo. The wiring harness originally has 2 wires coming from the connector into the harness. For some reason one wire has been cut on both primary injectors for who knows what. So only one wire is attached to each connector connecting to the primary injector. WHY!!! I guess the car still ran that way but I never saw it.

I can only assume they grounded the other wire. Maybe the original wire was all FUBAR so they decided it would be easier to ground them.

Ah thanks

I assume this harness was no in your car but you picked it up somewhere....becauses the injectors won't work with only one wire.

They might have cut the wire and had a 10ohm resistor soldered in b/t the injector and the 12v supply wire because they were using 2.2 ohm injectors on a series five car.

No S4 injector I think (its like brownish color. Their is couple series 5 things on the car like front cover but the Harness is N332 ECU

The N332 will work with low or high resistance injectors. But there's gotta be approx 12 ohms resistance across the injector.

Just put a meters pos and neg leads on the two blades on the injectors and see if they are low (approx 2.3) or high (approx 12).

If they're low, then you need to have a solenoid resistor pack in place or four approx 10 ohm resistors in line with the injector wiring.

well instead I will just make sure I buy a new S4 Wiring harness. That will solve all my problems. Hacking this car is what got it in the reck condition its in from the previous owner.
