OP...ask the advisors here who know more than the dealer tech who installed your
plug and play IBC to be on call to advise him HOW2...
Good luck tomorrow and since the dealer sold/installed said IBC, they
should make it good or replace it
Another point for your comparison between a MC PSI sensed vs
acelerometer sensed...the MC sensed will only provide as much
braking as the MC sensor says...or how much you are pressing the
brake pedal
An Acelerometer will sense the rate of deceleration and provide braking
power to the trailer based on that rate...factored by your preset (gain)
Bottom line...there is no one size fits all...even in shocks...
Whatever works for you is best for 'you'...it is your vehicle and your $$$$
PS...ask how much for an extra MC PSI Sensor. It should be easy to
change in a pinch. All of the hydraulic braking systems I've ever
designed...had those sensors leak over time. Not car stuff, but industrial
stuff...biggest disc was 48" in dia and biggest drums were in the 200-300lb
range
