Before you start
- Do not allow control module to be unmounted or tie wrapped behind the dash; control module will be stressed and failure will result.
- Do not use body bolts or screws on the dash; a poor ground will cause intermittent engine brake operation and damage to the control module.
Procedure
- Mount the control module inside the cab so that the harness will reach the dash module, using two self-tapping screws.
- Connect the wire harness, P/N 015683, to the control module.
- Connect the wire harness, P/N 015684, to the Weatherpack connector on the control module.
- Connect the RED wire to a 10 amp circuit breaker controlled by the key switch.
- The ORANGE wire is for an anti-skid system; if not used, insulate the end and store the wire.
- Connect the BROWN wire to the 3176 electronic control module, connection P-8 terminal C.
- Connect the GREEN wire to a good ground at the dedicated ground connection point located at the cylinder head.
