calling out to s4 t2's low impedence secondaries. where do u put your resistors?

caling out to s4 t2's with stock high impedence secondary injectors that has aftermarket low impedence secondaries. where do u put your resistors? i was told to put it near the ecu to keep away from the heat. but i dont have a fsm so i don tknow the ecu pinout. anyone can help? how about in the engine wiring harness? pics for both?

thanks

eric.

I agree the resistors should be located at the ECU.

Front primary: pin 3E, light green wire
Rear primary: pin 3C, light green wire with a black stripe
Front secondary: pin 3H, light green wire with a white stripe
Rear secondary: pin 3F, light green wire with a red stripe



All of this info is in the Factory Service Manual (FSM). Go to www.iluvmyrx7.com/2nd_gen_manuals.htm and download it in PDF format for free.

I put the resistors for my 720 secondaries at the ecu and they have been working fine.

I'm doing this today and this sounds to be the best way to go.is it true that you only have to put one resistor for the primary and one for the secondary?

No you need one for each injector you plan to use.
