Aloha,
My PC that runs RAVE in the shed is on loan......
Does anyone have a handy list of the (7, I believe) wires on the RH 2 plugs on the controller that need to have B+ and earth connected
to enable testing of the unit on the bench?
I have a couple of plugs to use for the test rig.
Going to overhaul 5 HVAC controllers and it would be very nice to be able to check out bulbs and display on the bench.

Power goes into C0792, the white central socket, not the ones on the RH side. It has an Acc (Ignition switch position 1) supply on pin 1, Ignition switched (position 2) on pin 3, permanent live on pin 2 and ground on pin 4. Backlight illumination supply (PWM Batt+) is supplied to pin 6.

Thanks!
I found an old thread on the dark side, then used the way back to confirm.
Got all of the pins I need except for the LCD screen backlight which is supplied separately...
Any idea what pin on the 20 pin connector that supplies that?
I am going on the video showing the test plug setup. He connects 2 wires from the 20 pin plug......
Without any 20 pin connector wires connected, the display works and all buttons check out fine, just gotta use a torch for the LCD.
I got RAVE to work on my really old XP machine and it looks like possibly pin 11? Don't want to fry anything though......

Got 2 fully refreshed HVAC controllers done.
3 to go
Oh, I did mean the Right hand most 2 plugs as viewed from the face. Should have said Center and RH plug.
I know the LH plugs are I/O

It does look like it is pin 11 on C0793 which is the 20 way one on the RH side. However, according to the description, it is fed with an "Inverse Pulse Width Modulated" signal so quite what it expects to see, I've no idea. I would pull the HEVAC out of a working car and test what voltage is supplied on that pin (Orange wire).
