Hi, i looked on the wire harness and there were lots of purples but no purple and white wires on it, i even tried the purple and white wire on the pcm and that did not work either, if there is any pictures or something i could look at maybe im looking at the wrong thing, i looked at the big wire harness above the transaxle but there was no purple with white on any of the wires just plain purple.
