Does anyone know the colors for the wiring in a 05 s4r that goes from the ecm to the tach and the one from the ecm to the immoblizer in the cluster? the tach sweeps but no work, possible broken wire? and the led on the cluster bliks once and then solid. the code says its a bad connetion from the panel to the ecm. did the red key procudure and eaven tried the throttle way but no luck.
