What the?

[0golf0fun]

What's going on here? This wire (looks like baling wire) runs from a plug, up and out of the doghouse to the windshield wiper control knob, where it was just hooked around the knob. Some sort of ground? Can I unplug this and toss it?
?

Determine the wire number from the silver tag at the plug. Then look it up here...

the plug is labeled 57f, pulled the wire from the plug, it was just shoved into the plug (the end put into the plug is pictured). Cleaned it up, looks to be copper.

So 57 is instrument panel ground, but the way it was set up cannot be correct. Any examples of how it should be grounded properly?

Thanks man, I appreciate your help

57F is the ground wire going to the WW motor via the contacts in the lower windshield.
it should be connected to those contacts

hmmm, do i need to fold the window down to get at the contact? Currently that plug, 57f, is the only loose wire in the vicinity.

I would assume the contacts are having issues and someone ran a wire outside the windshield to the WW motor.
That list is only gets you in the ballpark, the WW motor is grounded through the instrument grounding system, that is why it is labeled 57, F is the branch going to the WW motor.
The XXX are the contacts in the lower windshield.

Thank you Mogman, good info. I'm going to mess with it, see what I can do.

You have to access the contacts under the windshield, you are likely also going to have to drop the windshield to work on the contacts to make them work
the contacts are in the body directly under the windshield center post IIRC

Got them all plugged in, from driver side toward passenger side they are connected 57f, 27k, 71c. Did I read they schematic correctly or did i reverse it? should they be from the drivers side toward passenger side 71c, 27k, 57f?

 

[Mogman]

I am not sure if that is a direct reference to the order they are connected or not, do the wipers or squirters work?
Does the truck have a roof?

The wipers do not work, nor do the squirters. I was being lazy, I'll go ahead and drop the windshield. Yeah I have a soft top.

From Drivers side to passenger, it's 27(power), 71(Power back to washer motor),57(ground)

My immediate thought is that someone ran a “new wire@ because they couldn’t figure out the problem with the original circuit. Or, they found an unused hot wire (12 or 24 volts) and tapped in to it to power up something. Have you checked it with a voltmeter?
