TIPM/Modulite/Brake Controller issues
The part of my TIPM that controls fifth wheel right brake/stop light went out. All truck lights work normally. Dealer flashed TIPM but didn't fix it. Said I needed new $700 TIPM. Bought a Modulite after learning about em here/e-mailing with several others who have em. Installed Modulite today and now all trailer lights work properly.
However, now on my Tekonsha P3 brake controller, I get a red dial instead of normal color and it says "Short to Battery" or something like that. It says that whether the fifth wheel hooked up or not. I checked and rechecked my Modulite wiring multiple times. It appears to be installed correctly.
Any ideas? Must be related to the Modulite as the brake controller worked normally before I put it in.
Thanks.

With age comes the cage
When you hooked up the modulite did you disconnected the wires form the harness so as not to back feed the wires?
The P-3 has a self diagnostic feature to it have you ran it?

My neighbor has a '07.5 and a P3 that did the same thing, crawled all over his trailer and found a bare wire touching the frame. Pretty new trailer too. In your case I'd check the (blue?) wire going from the controller to the plug. I doubt it's the Modulite but maybe something got bumped/cut/twisted during the install. Gotta' hate it when you fix one problem and break something else
