Installing new wiring harness for heater blower motor and dash switch in my 68 C10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

HeavyHauler · Yesterday, 04:05 PM

Later this afternoon I will be installing a new wiring harness for the heater blower motor in my 1968 Chevy C10 which only came from the factory with a heater and no AC.

There is a brown wire that goes from the blower motor switch at the dash controls to the fuse panel?

I see the heater fuse in the panel but I am wondering how that brown wire connects to the fuse panel and where?

Any help is appreciated and thanks.

I believe this thread will answer your question. VetteVet explains it well.

Well I looked at my fuse box and I cannot find any 14 gauge brown wire coming from the fuse box at all. I looked at the heater fuse area and I dont see anything at all.

I dont see any brown wire coming from behind the box either. I know the brown wire is supposed to be coming from the fuse box as illustrated by the wiring diagram but I am not sure exactly where it should be.

Because if it is not there at all I want to put one back where the factory had it.

Scroll to post 6 in this thread VetteVet shows where the 14 brown originates in the fuse block.

It's possible that the 14 brown was damaged at some time in the past and was cut out like mine was. A PO of my truck cut the 14 brown off and spliced a new wire and plugged it into one of the unfused terminals on the fuse box. See photo. The small arrow points to the 14 brown where it goes into the heater switch plug. Where the PO spliced a blue to it and off camera a yellow wire was spliced to that.

The 14 brown should be coming out of the end of the main harness above the gas pedal.

In the second photo the green arrow points to the plug for the heater resistor. The red arrow points to the heater switch plug and the yellow arrow points to the #14 brown wire that comes from the fuse. Thanks to J2-72 for the photo.

I hope this helps.
