Ok, sorry to jump in on this late but I just got a couple panels with the swithes to put in place of the RAM panel below the radio. I originally was just going to us the one that had just heated seats and steering wheel. But when I pulled my panel of the wire harness matched up to the panel that had heated/cooling switches. It only has 3 pins as my harness has 3 wires. The other one had 7 pins I believe. I lights up with parking lights so wanted to buy the factor stuff to finish the job. Could anyone help?
