First off If you look in the FAQs you can find a copy of the Factory manuals. Get both, and compair the wiring diagrams, you can get all of the colors off of those as well.

Second. the S4 and S5 ECU connectors are not the same they use two different styles and cannot be made to work together. If you don't have a donor harness then you will have to find one, or buy the connectors somewhere. (hint I have some)
