On the pictures you can see up under the dash. The one picture is the back of the fan switch. The power from the fuse panel goes into this plug. Then the other picture is down by the fire wall. What needs to plug into this? I know for some of you this will be a laughing matter! I am no electrical gooroo! Thanks in advance for your help

The one in you hand goes to the resistor block in the bottom/back side of the heater box on the passenger side.

I been chasing my elect. on the 63 and none of the schematics have the heater/fan wiring in it . My switch wiring goes out the firewall and down to the starter area and back up by the ALt. So kinda lost allso

I will have to go back out and look. I looked all over the heater box and couldn't find anything to plug it into. Thanks, I will let you know what I find.

Yeah, I have searched high and low to find the wiring schematics for this and haven't found anything!

I think I still have a deluxe heater box in the stash and will try and get a picture.

These pics might help. Note the 3 prong silver connector of the backside of the heater venting.

It's good to have heat on a cold day. And I'm guessing you've got your share of cold in Idaho. Glad to have helped
