Need Help Fast...

[Frozen001]

So I gave my father my old Prodigy Break controller off my 2004 GMC Sirra 2500HD to use on his 2002 1500 Silverado... Apparently hooked it up and never tested it before oging on the road towing his camper he left about 20 minutes ago. As it is wired right now the breaks are on when the parking lights are on and not the breaks. The manual control works fine he said. I know he has to simply move one wire, but with out being there to see the acutal colors I cannot guide him. From Tekonsha's web site it looks like he has to move The RED wire on the controller to the BROWN wire on the GM harness... Remember the Harness came from a 2004 and his is a 2002. Apparently in 2003 GM moved some of the wires.

 

Can Someone confirm this??

 

Right now to stop he has to manually activate the trailer breaks....

Yes,They moved some wires in '03.

Give me a few minutes and I'll check which ones....

The way it is working it looks like the break controller red wire (Stop Signal) is wired to the illumination wire.

This should help ya'....

 

The 1999 though early 2003 wiring harness jumper that plugs into the relay block will have a reddish/brown 6-way connector and a tag with the last four digits of the wiring harness part number. Second design 2003-05 may have a white plastic connector with part number 5418 as well.

 

• The 1999 jumper is/was P/N 12171982 with a pink/purple tag identifier of 1982. This number has been superseded to 15366255, with a pink/purple tag identifier of 6255.

 

• The 2000 jumper harness is P/N 15366255. The pink/purple tag identifier is 6255.

 

• The 2001-2002 jumper is P/N 15086884. The orange tag identifier is 6884.

 

• The 2003-05 jumper is P/N 15085418. The orange tag identifier is 5418.

 

When transferring the brake controller with the wiring jumper attached from a 2001-2002 vehicle to a 2003-05 vehicle, a change to the jumper harness connector must be performed.

To modify a 12171982, 15366255 or 15086884 harness for use in a 2003-05 vehicle, switch the wires in cavities "A" and "D".

 

To modify a 15085418 harness for use in a 1999-2002 vehicle (see model list at the front of this bulletin for applicable models), switch the wires in cavities "A" and "D".

That looks like it will work...

 

Thanks!! Will update you if that is not it!
