Anyone else doing the Vintage Air A/C swap?
Just got my kit, and I already have the VA Frontrunner with compressor installed, so wondering how it went or is going for anyone else.
I've got a trans cooler up front of the radiator and a 3 core so test fitting the condenser will be interesting.
I will also have some trickiness with the Trinary switch wiring, I long ago cut back the harness to the firewall so I will have to figure out which wire(s) to use.
Cheers, Tim

Re: Anyone else doing the Vintage Air A/C swap?
We’ll need more information. Which system?, Gen IV Magnum?, Gen V?, SureFit kit?, are you using a VA condenser? The wiring is stand alone. The trinary switch is wired to the VA compressor clutch relay and the fan relay(s). The condenser can be bolted directly to the core support with fabricated brackets.

Yah it wasn't so much a call for help as it was anyone who had recently gone before me. I've got the the Surefit Gen 5 and their condenser. They've got good installation videos online.

Re: Anyone else doing the Vintage Air A/C swap?
The new surefit system seems great. I have the magnum IV which isn't nearly as plug and play and requires you to create your own custom plenums, panels etc. I am in the process of ditching the stock condenser for their surefit condenser kit. Caution, if you are LS swapped and running a GM E38 ECM, the output signal for fans could be PWM and not binary. Therefore making the trinary switch inoperable. You'll need to get creative and or go to a binary switch.

Firebird or Camaro? It took me two nights or so to install but everything went smoothly. I used both wires from the original pressure switch for the trinary.

I installed to full classic auto air kit. Very happy with it. Been running perfectly since 2016
