Where does this go?
I am putting my duct work back in my 72 Blazer with A/C and can not figure out for the life of me where this connector connects to. The high blower relay, fan speed switch and A/C switch are all connected. Anyone?

Re: Where does this go?
There is a resistor inside the heater box that looks like a spring or something. I think it may go to that.

Re: Where does this go?
The wiring connector is for the Anti-Dieseling Relay. If you don't have the solenoid on your carburetor with the connecting wiring you will not need it. The relay would normally be on the inside lower lip of the dash close to the controls.

That is clearly not the same plug as in the first photo. The wires are also different colors.

Re: Where does this go?
From my 71 service manual, the connector with pink, green and orange is indeed the anti-dieseling relay. This keeps the A/C compressor clutch engaged for a few seconds after turning off the ignition, which loads the engine enough to stop it dieseling. If the A/C blower switch is on, you will also notice the blower run on for a few seconds.

Re: Where does this go?
Thanks Jim. That was the one. No need for me to connect.

Re: Where does this go?
If you plan to hook up and use the AC, you will need that switch hooked up for the AC compressor to turn on. In the spring and fall around here, I reach under the dash and unplug mine so the compressor isn't on all the time

Re: Where does this go?
On mine, the relay switch is bolted to the bottom of the dash between the glove box and the AC controls. I forgot the exact name of the switch, it looks similar to the fan relay switch.
