Need heater wiring help 1960
 

I had to replace the heater switch assembly on my truck. With the replacement on I need to find out what wires go where on the heater motor switch. My old one was gutted, no connection pointa at all. I have three wires. orange, yellow, and black. The switch has 4 connector points Drivers side one obove the other, passenger side two side by side.

I`m looking at the AIM manual, it dosen`t show crap, showing a brown lead from the fuse block to the switch, then what it dosen`t tell is what three wires from the switch go to the resistor, (defrost element in the blower box) then one orange from the resistor to the fan motor..maybe this will help..:smoke:

It took a while to find anything, but this outfit sells a heater harness for the 1960 Chevy truck for $20. Part number is 38071. It might be worth 20 bucks just to know how to hook it up. Or perhaps with a phone call they might be willing to tell you how it connects.

I have the aim manual and it shows nothing of the fan/switch in any of the wiring schematics section except on one page and very vague, no colors except to say that its has orange to the fan and brown to power up. Strange.! So 62 GMC910 does the yellow / blue go to the heater defrost element in the blower box...?

Re: Need heater wiring help 1960
 

yes the blue and yellow go to the resistor panel and the orange is the hi which jumps the panel to the fan motor, can get the positions tomorrow if you need,

Thanks for all the info, mine must have been worked on. It has three individual spade conectors. The diagram of back of switch matches mine.
62gmc910 thanks for the pic if connector. One of mine might be blue or brown instead of black (wires old and dirty). I only see three wires exposed, one might be cut short. It just had a toggle set up for on/off.
Appreciate all the help.
