Well...I have to correct myself, a bit, on this one. I just checked the 7 way connector on my Solera. It appears that 6 of the 7 connections are standard - Battery, Ground, Running Lights, Left Turn/Brake, Right Turn/Brake, and even Backup. But it also appears that Brake Controller Output is missing.
