Brian, I too had issues and it gets very weird. First let me say I built my harness because I did not have one for the console in my truck as I did not have a console. I went to great pains to track down the exact connectors, pins etc. I used the exact gauge wire that was called out in the wiring diagrams, via the tech-authority website. And since I was doing this I even added the drops for the lighted sun-visors. This all came about when I upgraded from the RA1 to the RA2 and I noticed the "NO SIGNAL" on the radio when I selected the compass button. So I obtained a take out console with the compass module in it from a 2014. I hooked it all up IAW the wiring diagram and nothing. Its important to note that there are four cavaties in the module (+, _, line bus) cavity 4 is not used. I then got a hold of a home link module from a 2012, again nothing but it light up and I was able to code it and use it. So off to the dealer I go to get the home link sales code added, I also was having the sales code added for the CD player. The tech comes out and says you are all set. So I test everything CD player working, no compass, no homelink in evic and they just shake their heads, well at least the CD player is working.
Enough background here is where it gets weird, I swapped back in the 2014 compass module and on the way home the compass reading starts working in the RA2 radio but does not show up in the evic????
My next dumb move was to flash the RA2 with the latest update I lost the compass in the radio, this is a know issue.
But I figured that my wiring had to be right since the only way the radio could have displayed the compass heading was if the module was talking to the line bus.
So on to the present, the part number for the 2012 homelink module is different than the one used in the 2014, so I bit the bullet and bought a whole new console with the led lights homelink etc. When I plugged in the module and hit the homelink buttons the evic displayed them IE clearing channels, channel 1, 2, 3 training etc. So I felt much better still no compass in radio or evic?
I have upgraded to the RA4 and still no compass on radio or evic. I also do not get outside temp on the radio but it shows up on evic.
At this point I am thrilled that the home link shows up in the evic, but confused as hell as to why the compass does not show up in either the evic or the radio, and why the outside temp only shows up in the evic?
Any thoughts or ideas would be greatly appreciated.
FYI the masking tape is obviously temp as those clips once snapped into the mount are a PITA to get out.
Also I have since obtained a factory overhead console harness, which has only one drop for the sun visors an no drop for the cup holder light, mine is much nicer I think. But any way I tried this one with module and it worked the same way so it's not my wiring.
Forgot to mention sales code for overhead console is "CUN" home link is "CV2".
