Electronic Climate Controls with Aftermarket Servo HVAC

[buck19]

Looking for wiring interface from GM C5 corvette electronic climate control unit to run Vintage Air Gen II servo system. Anybody doing the electrical work to interface with the existing wiring harnesses provided by Vintage, Classic, or Restomod Air? The HVAC manufacturers want you to believe that only their controls will work with with their systems. Should be simple wiring to interface with other electronic controllers. Not that many functions to sort out for a qualified auto wiring tech. The HVAC companies would be ahead of the game if they would offer compatibility wiring plugs with the major auto manufacturers climate control units. They could charge the same amount for the wiring plug interface as they do for their billet dial controls and serve the restomod clientele at a higher level.

Any techs working on this type of project?

Im not positive but I believe all climate control functions are run through the BCM on newer cars and trucks.

Barrrf speaks the truth.When I worked for an OEM,we ran the actuators though the BCM along a CAN BUS. My current employer multiplexes HVAC operation for up to 15 actuator addresses through a 3 wire harness. Further, there are several fundamentally different types of actuators, and control logic varies with the different actuator types.

The problem I think for the aftermarket is they spend a couple hundred thousand dollars doing this for one OEM, the OEM builds the configuration for 4-5 years, then changes the way they control the HVAC. So your development cost gets spread across maybe a couple dozen cars.
