Grooming some wiring under the dash and found the heater resistor plug/wiring hanging back there. I looked all over my heater box for the connection and just plain couldn't locate where it goes..?
Any clues?

What year? A/C?

My 67 W/O A/C is on top of the suit case inside just to the passenger side from center. If you cannot find the 3 prong conector it is probably broken off of the fiberboard and fallen inside the suitcase as mine had done.

I guess that would be the unidentified hole on top of my heater box with no apparent purpose. I don't think I'm gonna go fishing for that, just tie-wrap those wires outta the way. Thanks for info.

Should be located in the heater or AC box just upstream from the blower. The resistor gets hot and the blower keeps it cool. That's pretty generic advice I know but represents the thought process I'd use to find it.

Len,

If you have factory air that connection does nothing.
If you don't, what Tony is telling you above is correct.
If you do not have factory air, that connection is to connect to the resistor at the heat box.
If your heat box has the resistor hole and you have factory air there were some changes made to your car. If that is the case, send me a private message and we can talk and I will be able to tell you what is up. A change was made: like a new wire harness was added, or someone changed to factory air (your cowl tag will clarify this) or your box was changed. Most likely not the latter.

How long have you had the car?

If you do not have factory air you have your answer. If you have factory air, I have lots of questions.

No factory air, so it sounds like it just dropped down inside, I found the hole on top of the heater box. From what I gather it won't keep the heater from working so I'm not gonna get too worried about it (being in SoCal has it's benefits)being a spot on install.

You can get the Blower Motor resistor from any dealership (they are still carried and produced by A/C Delco) I got mine from a local dealership that cost me $9.00. Then just get 2 sheetmetal screws and connect the harness connector and drop it into the hole and screw it into place.
It does control the speed of the blower motor when used.

Tony,
Thanks for the info, I'll look into that next summer when I take on the interior upgrade project.
