Hello: I have the above truck and need schematics for the hydraulic brake electrical. The brakes work fine when motor is running, but the electric pump doesn't work with motor off Key on or brake pedal pushed. I had the trailer charge line ( whoever installed it did not fuse it) short out and burned a couple of wires in the dash. I have a red wire going to the relay on the fuse box and I'll be darned if I can figure out where it goes. Plus I'm sure there are other things I've missed. Thanks, Terry
