Hey all!

I've been searching around for a few days now and I just can't seem to find an input/output pin diagram for the AC/Heating control unit in my Del Sol.
I'm trying to remove the whole unit and replace it with an Arduino so I can control it from a touchscreen, but I just can't make any sense of the wiring.
I removed the heating control unit and found that the wire harness splits into two connections on the back of the unit. One connector has 6 wires and the other has 12.

Does anyone have a diagram of what each wire connects to? I would like to recreate this system using the pins on my Arduino.
Any help at all would be much appreciated.
Thanks
This is the wire harness connecting to the back of the unit.

You can get the I/O information from the FSM. However, you may need to buy the Helms electronics manual.
