Thanks for the advice everyone. I should have mentioned I did meter the 7 pin connector and it was zilch. One nice thing is that they have the schematic embossed right on the plug cover (why didn't someone think of that sooner?) so it's easy to tell which plug is what. I did have the truck running when I tested it.
NChauler, I do have the 8.4" uconnect in dash information/radio whatever...I hate it, it's like touchscreen technology from 10 years ago. Why are automobile manufacturers so woefully lacking in consumer technology? Anyway, I have that, but not the backup cam or sensors. It's a 2013 (early year, not the 8 speed) ram bighorn edition. I had no idea ram wasn't dodge any more, lol.
So, now I'm off to locate and check that relay, thanks again everyone!
