Can someone please tell me where I can plug in my electric brake controller for my camper on my 2007 Silverado "New Body Style" truck.
Seems like the trailer dealer and my truck dealer can't figure it out because of it being the "new body style".
On my 2005 Silverado, there was no problem, just plug it in a harness that was hanging under the dash, alas, no harness hanging with the 2007.
The truck dealer said something about unplugging something from somewhere then plugging something somewhere else.
I'm really confused, I need this hooked up by Aprl so I can go camping.
I would appreciate any help, please e-mail me at: rheck53@hotmail.com

Thank you

I have the same question. I looked under the dash and only saw the ODBC II plug.

 

I've been looking also. The manual says there should be some blunt cut wires by the data link connector. I haven't located them yet. Should be a DARK BLUE, RED/BLACK, LIGHT BLUE/WHITE, AND WHITE. If anyone finds them I hope they'll let us know. I guess I'll call Customer Assistance and Information.

 

I got this tech bulletin from Prodigy. It is for 2007 Silverado.

 

This is great info, but hard to read. Can you send a link to the pdf file or send it to me?
Thanks in advance,
David

Underneath the dash find the parking brake release lever and go down and under from there you will find a bundle of wires that are taped up, fiddle around with them and you'll find that 4 wires (large red and blue and small light blue and wire) are cut with electrical tape on the ends, you can pull them out of the tape or cut the tape.
Sometimes these wires are closer to the gas pedal but still taped up and easy to locate.

 

The wires you refer to, are very easy to find. Like you said just under the dash, but mine were on the left side of the steering coluum. Also they will not supply any power to the trailer brakes till you hook up the two wires under the hood.

 

I have the same problem and I would also like a copy of the diagram if its still available. I did find the wires under the dash. Where are the wires under the hood that need attaching?

Thanks
