Injector Question...
I have a S4 jspec TII motor using a USDM wiring harness. My question is about the injector size. I had to cut the injector plugs off of the jspec harness and splice them into my USDM harness. The injectors on the engine (along with the harness plugs) are a magenta color. And I can't remember the USDM color....
So...what do you guys think?
What possible injector sizes could I have?

is this on a S4 or???
you shouldn't need to change the injector plugs, I suspect that you have a 87.5-88 engine and are using it with a pre 87.5 harness.

87TII injectors are low impedance and 88's are high impedance. You should never use low impedance injectors with a ECU that is mapped for high impedance injectors. However, you can use high impedance with a ECU taht normally uses low impedance.
In other words, the 87 and 88 injectors are different and I believe the plugs are aswell. Put a ohm meter to the injetor and see if it is high or low impedance. A low impedance injector is between about 2-5 ohms where as a high impedance is between about 12-16.
