EBPV Exhaust Brake

[ZCMiller]

I am wanting to turn the EBPV into an exhaust brake. I really want to run a swith, with the on being stock and off cutting power so that it never runs. I seen a guy who had a shift nob with a button run to control it when he wanted to use it as a brake. Is it possible to have it on a swith with on/off mode AND have it hooked up to a shift nob for brake purposes. I'm not an electrician by any means but I am capable of doing a lot of simple wiring. I hope my idea makes sense to at least someone.

yes it is possible. I have done it.

it involves 2 diodes, a resistor and the switch of your choice.

I don't have the schematic on my computer, but someone should be along shortly with the link for you.

i have the 5 speed manual trans and all i want is a on off switch nothing complicated....some pics of where the wires are would be great.

Hopefully this helps ya. Its in the 7.3 tech files section.

subscribed got the same thread going on here too want to do the same thing

the reason for the resistor is to drop the voltage, the actuator operates on 8v from the PCM, and the Diodes are to keep from back feeding the PCM and hurting it.

if i do it im gona cut any contact with the pcm and wire it up on a switch ON/OFF period....
