Yes. Its actually called the Brake Boss, or G2. According to everything I've read the P2 settings are basically the same. Boost is the initial minimum brake applied when the brake lights are activated then there is a Max setting to limit the total current going to the brakes to prevent lockup.
Looking at the pic in your reply my 5'er weighs a lot more so my settings will be different. My problem is with the boost set using the procedure in the instructions it works perfect during braking up to about 25-35mph. Above that speed the tow vehicle can't provide enough braking to get the accelerometer to raise the trailer braking much if any higher than the boost setting.
P.S. I recognize you from Cummins Forum, etc. I have another post there as well.
Thanks.
