This is a two part thread. One is the accomplishment and the other is a question.  I found one available Penguin II 15k btu unit nearby at a small RV dealer. I paid probably $400 more than buying it online, but they had it and I took it home. Got the hole measured, cut and wired in 2 hours with the a/c on the roof the next morning with my neighbors forklift. It's hot as blazes out here. I am happy with the install but waiting on a wifi thermostat to arrive next week. In the meantime, I have the rear t-stat which is the ccc Dometic with the 4 pin RJ11 plug as a test mule. I ran a blue cat5 wire from the t-stat location to the roof air all fished through the ceiling. I need to convert the blue, blue white/ orange/orange white to the black, red, green, yellow of the phone plug that I cut off from a phone patch cord. Not sure how to wire that since Dometic shows the plug in opposite orientations. Can someone spell out how I need to wire the t-stat color code? I can decipher the dometic wiring to my cat5 colors.
