Hey,

I just purchased a 97 expedition and the previous owner pulled the wires out of the back of the switch while installing a radio. I know where the light blue and black wires go but there are 2 dark blue wires and I was wondering if there was a way to figure out which one goes where or does it matter. Neither one has a stripe just solid dark blue, and they should go in the two center locations of the plug.

Thanks,
James
