Another question. The ITBC gain setting is voltage and the maximum is 10V but the break-away switch delivers 12-13.5V. I found a transformer that steps up 9-18V to 12.5V at 16A max. If I wired this inline before the 7-way plug would it work? I realize I would lose any adjustment between 9V and 10V and would have to insure there would be pass through voltage up to 9V.

I am surprised: 11.9V. I thought that the gain was voltage as page 200 in the owner's manual refers to "power" output adjustment with the manual slider. So, if the break-away switch puts out 13.6V and the manual slider puts out 11.9V the difference of 1.7V should not account for the difference between the break-away switch locking the trailer brakes and the manual slider not locking the brakes. There has to be something else affecting the performance of the ITBC.

if you can verify 22 amps, the only thing left is adjusting the brake shoes. Otherwise that's all she's got.
