Ford F350 Power Stroke Brakes Wiring
Wiring and air lines from the underhood components are routed along the passenger-side framerail and wrapped in a wiring loom (save for the preexisting blue wire on our subject vehicle that is routed to another accessory). These will be attached to the frame-mounted control solenoid and brake valve. Also note the air line with the yellow tip-it's the vent line for the air cylinder that admits/releases air as the cylinder cycles. It will be routed to a location under the hood, away from moisture and dirt.
