5 button thermostat phone lines
I have a 2003 38' alpine that has the original ac units with the 5 button thermostat. I removed the rear ac unit to reseal the unit and the phone line that controls the unit from thermostat has the wires crimped where you can see the wire colors. Turns out these wires are very fragile and some of the wires broke off at the crimp. The only wires still connected were a yellow to black wire. i found 3 crimp connectors so idk if all 4 wires were connected or if all four are needed. I wish i would of taken a picture of them but i didn't. I looked at the phone line going to front unit and the wire colors match. So the back unit is wired differently than the front unit. I was wondering if anyone has experience with these wires or could possibly look at theirs and let me know the correct wiring..carefully. They can be accessed under the filter cover. Thanks!!
