Advent Air Conditioners like part # ACM135 come with a connector that pairs up directly with the standard 6-wire connector. If you have a 9-wire connector then you need the kit # ACRG15 as well.
For wiring I'm attaching some photos of diagrams for you to reference. We typically recommend having a professional do the installation so if this is something you've never done before I recommend at least having someone who has done this type of installation before come out and walk you through the process.
Attached are some review videos for you to check out as well.

I have installed a new advent unit and the compressor is not coming on. I used the install kit to use the Coleman Mach control box and t stat. there is 120 power going out to compressor wire .

I have checked out the voltage for my unit and it says that it has 12 volts , so why is it still reading low voltage?

I had to remove my ducted Advent a/c unit and replace with an OutEquip low profile non ducted unit. I just realized my gas heater was run through the Advent unit. Is there a way to run the gas heater without the Advent unit ?

My client purchased and installed the ACM150 on the roof of their RV and ACRG15 inside of the RV. We have 120volt to the ACRG15, T-stat is wired according to the wiring diagram, but we have NO power to the T-stat. What am I missing?? Sincerely
