Has anyone installed the accumulator themselves? I understand for my build year (12/99) I need to do the electrical wiring for the value and have the dealer turn it on in the main computer. How difficult was the job? Is air a concern in the lines? How long did you let the car sit before messing with the oil lines? Also, can anyone provide the "pin out" of the accumulator? What color wires go where on the clip to the accumulator itself. If anyone know, is it possible to buy just the wire harness for the accumulator? It seems that online parts dealer have it as a whole set...
