Turn off the negative cable of the battery, separate it from the car and isolate it and then remove the shield and battery. Dislodge the vacuum hose connector at the tank built into the
Battery Tray, remove the screw holding the engine coolant to the battery tray and remove the battery tray. Press the brake pedal down at least one inch with a brake pedal depressor to keep the brake fluid from being drained out of the master cylinder when removing the brake tubes from the HCU. Don't attach a 12-volt power supply to the CAB connector when it's unplugged. Cut the speed control wires, hang the servo aside and take out the nuts holding the servo in place. Remove the 24-way connector from the CAB by pressing up on the lock to release it. Use Mopar Brake Parts Cleaner to wipe down all the ICU and tube nut surfaces, before removing the brake tubes from the HCU's inlet and outlet ports. Securely center the
Steering Wheel, remove the panel located underneath the instrument panel, free the steering shaft coupling pin bolt and unfasten both the clips and screws that hold the silencer to the dash seal. Unscrew the bolts that join it to the bracket and bring the ICU down through the engine bay. Set the ICU into its bracket beneath the master cylinder and then start installing the upper mounting bolt. Within the vehicle, fit the final two bolts into the bracket and tighten all three to 11 Nm (97 in. lbs.). Install the dash seal and three screws, followed by the silencer above the seal. Bring together the steering shaft coupling, fit the pinch bolt in place, then clamp it tight with 28 Nm (250 in. lbs.) force. Slip the silencer panel onto the steering column again, remove the braking pedal holder and be sure all tubes are set up in the correct direction so they do not make contact with the other components. Fit the main and secondary brake tubes into the HCU valve block at the right connections and tighten the tube nuts to 17 Nm (145 in. lbs.). Attach the four chassis brake pipes to where they belong on the HCU valve block and tighten each of their nuts to 17 Nm (145 in. lbs.). After putting the seal in the main connector, insert it into the Comms Avionics Bay socket and push it down to the bottom while locking it into position. Add any special routing clips to the brake tubes, take off the brake pedal holder, set up the speed control servo with its nuts and attach the wiring harness again. Place the battery tray back, attach the coolant filler neck screw, join the vacuum hose once more, put the battery and its cover into place, reattach the negative cable, drain and top off the two brake hydraulic systems and drive the car briefly to ensure both systems are working smoothly.
