Hello, I am new to Ram forums, I find it very interesting and informing. I have a 2015 Ram 1500 Big Horn, and I have installed the Auto High Beam control mirror in my truck, used Alpha OBD to activate it and it works great. Now I would like to install the Auto Wipers, but I am wondering what part number harness to use. I have dual climate control with humidity sensor in my truck, factory installed. The auto High beam mirror I got from a 2016 Ram came with the harness from the 2016, which does not have the humidity sensor plug, but has the auto wiper plug.
My question is, when I compare the wiring between my original harness with humidity sensor but no auto wiper plug, and the 2016 harness without the humidity sensor plug but has rain sensor, it seems they use the same wires?
In the pics I included, the 2 wires on the left of the plug in pinouts #2 and #6 on my truck (I think the colors are (#2;Pink with yellow trace, #6;Orange with blue trace) go to humidity sensor, where as the harness that came with the mirror (harness on table top) those #2 and #6 wires are the same color, but go to the rain sensor, so, does that mean I just need to splice the auto wiper sensor to my harness? Another thing is on my harness, in pinout #1 I have an wire, where the other harness does not.
Any help would be appreciated, and hopefully helpful to others running into this issue. Thanks for your time.
