Yes I have this harness and it’s connected. After the connector, it splits in 2: one red and one black on each side
Look at the wires coming into the connector. There should be two greens, a black, and a purple.
If you look at the back side of the incoming half of the connector with the sockets in it, the pin positions will be marked 1 thru 4.
Identify Pins 1 & 2. That should correspond to wires 180 Green and 200 Black. Turn on the key and measure the voltage between those two wires. Do you have 12v.? If you don't try going back to the fuse box and check that the fuse #7 (15-ampere) for the air ride seat is not blown.
Give both halves of the connector a good clean with some aerosol contact cleaner, hook everything up, and see how you go from there.
