Question:
I will be installing this along with the Tekosha Voyager ID but realized I will also need a flat-4 trailer connector. Is there a different trailer connector that has both 7 and 4 way that will use the Tekosha wiring with the pins attached for the 7-way. Or should I just use a 7-4 plug-in adaptor?

Hey Robb, I have a solution for you but there isn't a different version of the # 22112 that comes with a 4-way and a 7-way so what you would need to do is get the Curt # C55774 with the kit and then swap out the 7-way that comes with it with the # C55774 and you'd have what you are looking for.

Hey Robb, how did things go with the Curt wiring harness and the Tekonsha setup? Did swapping in the Curt connector give you the 7- and 4-way combo you needed? Your update could make it easier for others working on the same wiring setup.
