You bet Clarke, not just for us but others as well with 6V92 and 8V92 and earlier 71 Series as well as some Cummins or Cats. This does make me re-think leaving it on all of the time. This would make the Solenoids come in every time we decelerate. I am thinking of turning the Jake Brake off when on a long run and not when needing that extra help.

Those Solenoids are most likely the same ones used on Cummins and Caterpillars though so may be readily available.
