Which two injector clips on a S4 TII are ihe primaries and secondaries?

The branch that has 2 injector clips and the coolant temp sensor is what?

I have begun the install of my Greddy V spec FMIC and have a question. Do you have to remove or modify the brake vents (black plastic scoop-like) ?

Thanx

the lower injectors on the US spec Turbo engines are the primaries.

hmm, I'd have to look to see what you are talking about

Yes, you would need to remove the tubes from the openings to the brakes.

I am trying to figure out which injector clips are for the secondaries/primaries. I am installing a S4 TII engine harness (from passenger side firewall) harness into a NA base.

The harness branches off in five (I think) branches.

1. To MAF (right front corner of engine bay)
2. Solenoids
3. 2 Injector clips with coolant temp guage (on back of waterpump housing)
4. 2 Injector clips with several other connectors (oxygen sensor)
5. Miscellaneous clips, including a grounding point

Thanx

You do know that the factory manuals are online and will have the injector wire colors, so that you can just look at the manual and see what injector gets what plug?

I found it........

Here is a injector diagram showing what my original question was looking for, and that is the injector clip positions. The water thermo sensor which connects to the back of the water pump housing is branched off with the front primary and front secondary injectors.

I love this stuff.......that is, learning something new

I hope this helps someone else as well.

Thanx to all who posted.
