Disconnect the negative battery cable. Label and detach all wiring from the ICM. If the module is mounted to the inner fender, remove the ICM/heat sink-to-fender apron bolts, then remove the ICM/heat sink. If the module is mounted to the intake manifold, remove the ICM/heat sink-to-intake manifold bolts, then remove the ICM/heat sink. If necessary, at this time the ICM can be removed from the heat sink. Apply an approximately 1/32 in.(0.80mm) thick layer of silicone dielectric compound (D7AZ-19A331-A or equivalent) to the base plate of the ICM. Install the ICM onto the heat sink. Tighten the mounting bolts to 15-35 inch lbs. (1.7-4.0 Nm). Position the ICM onto the right-hand, front fender apron or intake manifold, then install and tighten the mounting bolts to 90-120 inch lbs. (10-14 Nm). Attach all wiring to the ICM, then connect the negative battery cable. Disconnect the negative battery cable. Remove the distributor assembly from the engine. Place the distributor on the workbench and remove the module retaining screws. Pull the right side of the module down the distributor mounting flange and back up to disengage the module terminal from the connector in the distributor base. The module may be pulled toward the flange and away from the distributor. Coat the base plate of the TFI ignition module uniformly with 1/32 inch of silicone dielectric compound WA-10 or equivalent. Position the module on the distributor base mounting flange. Carefully position the module toward the distributor bowl and engage the three connector pins securely. Install the retaining screws. Tighten to 15-35 inch lbs. (1.7-4.0 Nm), starting with the upper right screw. Install the distributor into the engine. Install the cap and wires. Reconnect the negative battery cable. Recheck the initial timing. Adjust if necessary.
