I know this may have been asked already but I did a search in the post and threads and could not find what I was looking for.
I was under the dash yesterday looking for a connecter from the stock wiring harness on the truck and could not locate a connecter. I did notice a blue connector that might fit the wiring harness for the Prodigy brake controler but this seems to be in a different location then what I have read in other threads. The connecter is located to the left of the brake pedal on top of a electrical sensor by the parking brake. This seams to be the right size but I do not know if this is the correct one?
Has anyone wired a braker controler to their 2008 Dodges yet? I have a 2500HD Mega CAB CTD an I am trying to get the truck ready for the camping seanson. Any Pic's would be helpful.
Thanks in advance

 

I don't have a megacab but with the last 3 RAMS I've had from '99 to 07.5 the Blue wire connector you're talking about IS the brake controller hookup. The last 2 trucks it was a pain to get to, stuck up high in the wire abyss by the brake pedal. I believe the connector is "idiot-proof" meaning the brake harness can only fit 1 way.

 

I have a 2007 Mega and the blue connector is the one you want - plug and play. It may be tucked up high like the other poster stated.
