if you have the 1500 based on the GM900 platform, then there's a fuse in the engine compartment, that needs to be activated for the controller to work.
this happened on my 2007 Avalanche when i hooked up my Prodigy BC. nothing happened until the RV shop found out about this inactive fuse.
even the local Chevy dealership service dept. were unaware of it.
