6- Starting from this point, route the Cylinder Head Temperature sensor wiring harness to the sensor. Make sure it does not contact any moving or
hot parts. Use wire-ties to secure the harness along its routing.
7- Next, route the Knock Sensor wiring harness in the same way. Be sure to use wire-ties to secure the harness along its routing.
8- Connect the 32-Pin connector to the module as shown in Picture 5, below left. Listen for an audible click to confirm the connection. Next, with
wiring harness run to the sensors, connect the Knock and Cylinder Head Temperature sensors as illustrated in Picture 6, below right. Again,
listen for an audible click when they connect.
9- Now connect the 12-pin connector from the IST harness to the stock Harley-Davidson® harness as shown in Picture 7, below.
