how to

[jimmys f250]

I have a 95 dodge with a cummins, well when i bought it the former owner threw in a bd engine brake, they rebuilt the engine and didn't put it back on,,the switch is still on the dash but was wondering where to get vacumm for the brake,

Not sure exactly how the engine brake works since i haven't messed with one. But i know on my 96 the vacuum can be obtained from the vacuum pump inline with the steering pump. Pretty much has a direct line from itself into the brake booster and off to the transfer case switch to lock the front in for 4x4.

just splice into the vacuum line that goes to the heatercontrols and the CAD. that will give you vacuum.
