I recently purchased a new ECC unit from Erie Vovo and was advised that since the replacement came from a 95 850 and I am installing it into a 93, there was a small change needed to the wiring harnes. They included a wiring "kit" but no instructions as to the changeover. Has anyone done this change or have a diagram of the wire to switch? I need to get the unit working again as the hot weather is moving in fast.
