2005 & Prodigy wiring ???

roger45 · 09-07-2007, 02:54 PM

My buddy bought a Prodigy controller for his 2005 2500HD with the wiring pigtail. The box for the pigtail said it was for a 2002, but the salesman said it matched in his computer for a 2005. Does this sound right? The instructions said to plug it into the electrical panel under the dash, top left, second plug in. I then tested the wires with a meter and the Black was the only *hot* wire. Installed the Prodigy, plugged its wiring harness in, then attached the four wires to the factory wires (Black to black, etc). The unit came on as the instructions said

. Last I popped the hood, opened the big fuse box, removed the plug on the top left, then installed a 40 amp fuse.
Any mistakes I made??? We won't be able to plug it into a trailer until next week...but I think it is good to go

Sounds like you got it all covered, but i have never installed a prodigy, but i wouldent think its any different than any other good controler!

Thank goodness for RV.NET forums...lots of people there were eager to help with my mistake...GM has two different wiring pigtails sold and I had the wrong one. The guys on that forum sent me the links I needed to correct the problem:cool

Hey Roger45, I just yesterday hooked up my prodigy from a 99 Silverado to my new 07 LBZ Siverado and couldn't figure out why I had no Brake lights, Right blinker and the controller was showing eronious readings. I too found out the difference in pigtails! Just changed out a wire to the "A" slot..(found out through local shop here) and back to normal! Heck of a note to think some of the things I was thinkin!!! Glad it worked out with you as well
