I have a few questions sorry ,I am trying to get this truck figured out so I can get her back togther and running.

1. On my wiper motor under the dash there is a plug I know where it goes but there is a single wire with a black stripe also where does it go?

2.blower/ac -there is a plug with 3 wires,orange,yellow,red with black stripe, where does it go?

3.blower/ac- female plug, has2 redwires with black stripes where des it go?

4.blower/ac- male plug single thick brown wire, where does this go?


Thanks for looking any help is greatly appreciated, never sene a tuck with so many wires before.

 

I'm not a guru, but this is like the stuff I study in school (industrial controls). So, here's your tax dollars at work!
I found this info in my Haynes manual for '75-'76 truck:

1. With a two speed switch: GR/BK to washer pump.
Two speed with intermittent: GR/BK to washer pump, W/BK-power to governor and switch. These are the only wires with a black tracer.

2. O, R/BK, Y/R go to the accessory safety relay. Y/R is the control wire from the mode switch (AC, heat, defrost). The O and R/BK are the switched circuit. O is hot, R/BK is the power feed to the blower switch.

3. One is the R/BK in #2, the other runs parallel to the blower resistor. Diagram shows them joining with an orange(?) wire-power to the blower switch.

4. The only plain Brown wires on this diagram are associated with the running/marker lights.

Make sure you have adequate light, and take a few breaks when you work on stuff like this. It helps keep the smoke in.

 

thanks, yeah i dont wnat these wires getitng toasted when i got the truck it had a hacked harness and it shorted and toasted thre wiring thats why im in this pickle now, thanks though.

 

Glad to help, looking over diagrams keeps me sharp on ladder logic. Feel free to email me if you need more help. I check mail almost daily.
