Neil F, what did you route the supplied orange wire into? The Mopar instuctions showed using an orange wire bundled to the connector on the Heating/AC Center Switch. That wire was orange, with Blue striping. When I used that wire, the defroster switch was on all the time, and I could not shut it off by pressing it again, or even shutting off the engine. That orange wire I used must have been the problem? Or the HBL Relay wasn't working? I'm not sure what to point to as the problem.
