This post above gives me hope!
I have a 2020 1500 and purchased the module. Got all excited - hooked it up and blam!!!! Got the same old test lights when entering trailer mode. No expanded menuing…. So begs the question. I see the wiring diagram - can’t for the life of me figure where or how to install the extra power or ground. Any pics or extra info on that maybe?
and then - the connector that you got from Amazon. What was that for specifically? Any link to that? Or was that a nice to have not a need to have.
Hoping that this extra wire attempt gets this going for us - am anxious to be a little safer riding the camper and knowing how those wheels are doing!
