Exhaust brake 12 volt power source
I am trying to find out where the 12 volt power for the exhaust brake air valve solenoid comes from. Where would a fuse be located?

- Reasonably complex, since the signal comes from the exhaust brake switch AND the throttle AND then through the transmission ECM through at least one and generally two relays.
With a 1996, you may still be on a Freightliner chassis. If so, they can provide you with a wiring diagram.
