AC Heater System Wiring Schematic

[zout]

I'll try to be a benifical help to SS by posting this.

Here is a copy of the wiring schematic for the AC/Heater Blower controls ONLY
for the ac kits being sold out there.

You will need this when you go to fabricate in anything less than what this kit was designed
for. Note the wiring placement on each relay and what its position controls.

This was sent to me under permission of its designers offices - so there is no copywrite infringement here.

Hopefully someone smarter than I can get this into a TM of some sort here.View attachment 20130312122026875.pdf

what a/c kits is this for? what was the original vehicle?

Once again - this kit is specifically made for this big SOB.
But -the kit can with some work be retrofitted into other trucks if you stick at it and know
how to fabricate - some knowledge on ac systems helps in the process as well.

Does this wiring apply to red dot a/c unit being modified for a 931a2? Thanks

This is what I needed a couple of weeks ago. What I need now it the cooling side of the wiring diagram if anyone has it. I believe the kit I have is the MTVR under dash unit

Did you ever get the wiring diagram for the Red Dot underdash AC system ? My S&S dealer is trying to make the AC clutch come on after his install. Thanks, Dan C.

Thanks - this is very helpful, especially given it is legible and wire colors are noted - have a great weekend !

I got the other schematic from a friend on FB that contains the motor blower assembly, switches, thermostat, condensor and compressor relays, and actuators - let me know your email and I will forward it to you. Dan C.
