Installation
FASTENER | TORQUE VALUE | |
ECM caddy fastener | 72-96 in·lbs | 8.1-10.8 Nm |
1. See Figure 6-104, Figure 6-105 or Figure 6-106. Loosely position new main wiring harness on vehicle. From left side, slide ECM caddy (XL models) or H-bracket (XR 1200X) (1) into position on rear frame downtube. Guide each wire bundle toward its respective area on the vehicle during installation. Verify lower right bundle (3) feeds out toward right side of vehicle.
