CAUTION

Hold the knock sensor in position by hand while torquing. Do NOT use pliers. Damage to the knock sensor will occur.

NOTE - Red Loctite® is not recommended for fasteners into aluminum.

WIRING HARNESS ROUTING

1. Connect the black, plastic connector of knock sensor wiring harness (k) to knock sensor (a) to determine harness length available to route to

the Engine Control Module (ECM).

2. Locate the ECM. Usually, it can be found under the right side cover (Touring models) or under the seat (Harley-Davidson® Softail® and Dyna™).

Consult your factory manual if you are unable to locate the ECM.

3. Route the wire so that the exposed terminals of the knock sensor harness are near the gray, 36-terminal ECM connector.
4. Verify that there is enough slack in the harness to allow for engine movement. Also be sure that the harness is secured with the supplied wire

ties (j) so that it is not touching any hot or moving parts of the engine.

ECM CONNECTOR MODIFICATION (Insertion of knock harness terminals into ECM connector).
1. Cut the wire tie at the base of the main wiring harness where it meets with the 36-position gray connector.
