I just bought an 84 a few weeks ago and the dude that owned it was a tweaker. I've been removing all of the crazy crap he rigged up in the truck, and found that there was nothing connected to this pig tail. He rigged some stuff for the heater blower instead or replacing a broken resistor, so I figured it might be for the blower, but the pigtail is too short. does anyone know if there is another section between this connector and the blower?

 

Do you have A/C? Mine has all the wiring but no A/C

 

I rid of the a/c when I bedlined the cab, but there wasn't anything on the a/c box that used a plug. I know it isn't for the heater now either. I also have two mmore smallplugs underneath the glove box that don't have anything to connect to either.

 

I've got a few unused plugs under my dashes on both trucks with what looks like factory tape on them tying them back to the harness.....
Hold on I'll snap a pic

 

Kinda hard to see but maybe it'll help

 

I've got those green ones going back into the harness also. I don't have a wiring diagram either, so I'm not sure what they are yet.

 

I hate trying to fix someones goof-up. Hope you get it sorted.

 

Every time I get something fixed, something else comes up. This dude just tried to hide one thing under another. So far I've eliminated around 12 ft. of wiring and three switches.
