I followed the instructions the best i could, but my car wouldnt start. Frustrated, I whipped out the trusty manual and compared wiring diagrams between the two series(s4/s5) and made my own wiring decisions, pulled codes and made more wiring changes.



so here it is kids, the definitive wiring instructions!





...........S4................................S5... ..........

GRN/ORG...............+.........GRN/ORG

............BRN/BLK+BRN/BLK.......................

............BRN/BLK+BRN/BLK.......................(join these four wires together)

GRN/BLU................+........GRAY(green wire inside gray insulator)

BRN/WHT...............+........BRN/WHT

BLK+BRN







note: my car has a 87 wiring harness-- according to the book the wiring is different between 87 and 88.

hmm... did the mod from s4 to s5... doesnt want to idle right. it will die if i let off gas and when i start to go it sounds like it only runs on one rotor... but after like 2 minutes with my foot on the gas it will idle decently
