i dunno either, maybe cause mine was a s model or mabye cause it was automatic. who knows. either way i didnt do ish with it. connected the other two together, found out my ac button doesnt work on my unit and also the heater valve solinoid only works at 18 and since my unit works backwards i winded up wiring those two wires to a switch which goes to the ground. guess what. ac kicks in

yay for me. my ac fan was broken though so when it started turning it was loose and melted spinning against the radiator. so i took that out. now i just need to find my ac leak and i will have a working climate control. no auto feature yet till i find a way to reverse the air mix motor. i just need some sorta ac for now. need to probably get yet another unit too. one with a working ac button so i can rid the switch. but i now have a working unit that blows cool. yay for me. forbidden, you need to get your ass in gear. need you to figure out the air mix motor. reversing the wires didnt work.
