    If you are using a trinary switch, the blue leads are for the fan and the black are for the compressor clutch. The switch I used didn't come with any instructions but these seems to be the standard.

    No. No trinary. Just binary. I just screwed up and put the the switches in the wrong places. Simple fix. Hopefully that's the only issue with my ac install. Hoping it blows cold as a witches titty. Lol

    It likely will at the vent. Unfortunately you'll be sitting about 3' from the vent and by the time it hits you it'll kind of coolish. At least that's the way mine is.

    Thanks for all the input guys. From what I know about the ac units the gen 2 is a higher btu than the gen 1. So i am pretty confident it will cool the cab pretty well. I have insulated the cab and modernized it as well. Seats. Carpet. Headliner. Etc. I'm hoping it's similar to a semi

    I spoke with an ac specialist today and we discussed matching volumes of different components.

    There has been discussion in this thread about the stock condenser and two different MRAP condensers.

    I am curious about the two evaporator volumes and the three condensers people are using.

    Anyone have the full specs on these units? I have heard rumors of 26,000 BTU for the gen2 ac. Is that a real number? Anyone have the full specs?

    What brake valve are you using with the gen2 ac units? I heard that it was necessary to upgrade to a different parking brake valve.

    Here is the description of the valve I used.

    Haldex Midland Manifold Valve 3064940 Parking Brake Trailer Air Supply Military

    Should be available on the popular auction site for under $10.

    Also here are the spec from the A/C unit drawing, the Gen 2 is the R-5760-0
