I didn't do that vital first step and ended up driving myself crazy trying to figure out where I screwed up.
I did check for connectors - both were there, so I shopped around and found a local parts store that had both controller and bezel in stock.
I got it and installed it yesterday.
This is what is happening when no trailer connected:
The controller lights up for a second or so, when I turn the ignition key, then it turns off.
As soon as I press adjusting buttons (+ or -) it lights up again for a while and turns off again.
I'm assuming that this is all correct, but I haven't tried to tow anything yet.
Can someone with installed, working controller can confirm this?
Also, I need to find someone to flash the truck software, so I can see it in EVIC.
