Well.....got'em installed, but managed to fry the switch. The mirror side of the plug didn't match the wire diagram. Figured that out too late. Down...I mean Up works real good. :) New switch going in tomorrow.
I just got in a set of Dodge tow mirrors today. Got them off Ebay for $179. I'm exited to have found this thread. Excellent post! It'll help me do the swap on my 99 GMC Suburban K2500 this weekend. I also have a 2007 Dodge 2500 and the tow mirrors are awesome. Can't wait to roll down the road...
