Hello,
I have a 2011 GMC Sierra HD...
The module is programmed and responds to the factory key fob. When I press the unlock button, the blue LED light flashes and the locks work.
but when I press lock button three times - It does not inittiate start sequence. I currently was trying to hook it up with no peripherals, just the module connected to the transponder and ignition.
Am I missing a step?
I noticed on the harness there are two male connectors left that I have no place for under the dash,
and a two pin female connection on the module that does not seem to be for anything under there as well.
Please advise. thanks
