its not fully stock... and when another well educated wrench head took a look at the truck a little back, he said it had been fitted with a much larger brake booster. I inspected all around and couldn't find any type of switch or electrical wire near the brake arm, linkage, etc... there is some solenoid/relay "thingy" between the arm of the brake and clutch on the firewall that has two wires going from it direct to the fuse panel? but there is no protruding arm or anything from it. ?
