you need to make your EBPV work as the brake...search the 94-97 forum...should be some good directions in there...i pickup up all the radio shack parts last night for bout $15...plannin on wiring it up tomorrow...i'll let ya know how it goes when i get done

Here is a switch that would work perfect for that application. I used the exact same one but it said engine brake high/low on it. These are the top notch switches. I just didn't want some cheap chrome toggle switch for it.

i plan on doing this when it warms up

its super easy to wire up a switch. i did it on my truck. youll see a small 2 wire electrical connector under the compressor housing of the turbo. i cut the connector ends off and crimped on blade connectors to the side going to the actuator. i just left the other side sit there.

i ran a wire from the battery to the actuator to make it hot at all times, and put a 20A switch in the cab to a good ground. it took maybe an hour to do everything and its wired up retty clean and can barley see it.

i love it for cold winter mornings. warm up is really quick. slowing down a big hill is fun too LOL drop er in 3rd gear flip the switch and it hauls you down pretty good without touching the brakes

holy dead thread revival!
FYI an exhaust brake is not a "Jake Brake"
a jake brake, manufactured by jacobs industries, is an engine braking system that actuates the exhaust valve to relieve compression and gain compression.

The EBPV mod is an exhaust brake, restricting exhaust airflow.

Thanks for pointing that out. While jacobs does make both exhaust and engine brakes, a true Jake is a compression brake, not an exhaust flap.
