Thanks! I do not have the back up sensors so I guess that might be it. The dealer service dept told me that all express vans were prewired for towing so it that would be disappointing if it wasn't! We will eventually be towing a travel trailer with this and I was thinking it would be prewired for it (brake controller wire, etc.)

Although I have a bumper mounted, 7 tab connector for towing (indicating a heavy duty trailer package) I find no trailer brake controller obvious on the truck. The power wire is NOT connected. Is there the probability that my just-aquired 1500 Silverado LT4x4 auto 5.3 with six speed automatic and trailer button on the shift stalk does NOT have a controller?

just because it has a towing package does not mean its brake controller equipped.
post in the Silverado section and provide the model year.

I have a 2017 express passenger extended (3500) that I just bought used. It has the tow button and the wiring harness under the dash. But I cannot find anything that matches what the 7 pin connector should be. There is a six pin connector that I'm sure after reading this thread is for some backup sensor I dont' have. I have put a voltage meter on the wires under the dash (that do match what should be there to connect a brake controller, I get nothing. (engine running and not). Any help with this is greatly appreciated. I'm having a really hard time believing that GM builds a vehicle with the tow button, and some wiring under the dash, but doesn't complete it. I badly need to get his working. This is pretty much BS.
