STEP ONE
Lower spare tire for access to winch mechanism and winch tube.

STEP TWO Place the U-shaped bracket over the winch tube, with the round hole in the bracket leg facing toward the right side the truck. Hold the lock bar horizontal and let the flat machined end engage the round hole in the bracket. Rotate the lock bar until the flat machined end is aligned with the flat sided hole in the opposite leg of the bracket and then pushing the end of bar through flat sided hole and letting the lock bar swing downward to a vertical position which will lock the end of the bar into the U-shaped bracket.

STEP THREE
Release and let the spare tire swing back to the horizontal position. Raise the spare tire as you guide the lower end of the lock bar into the lug hole least obstructed by the winch cable mounting plate positioned in the center of the wheel. Prevent spare tire from rotating, to insure that the lock bar remains vertical as spare tire is raised to the full up/stored position.

STEP FOUR
The PVC lock bar cover/seal is designed to center and hold the lock firmly against the tapered surface of the lug hole. Hold lock inverted with the PVC cover/seal end up. Place lock over the end of the lock bar. Slide lockupward against the tapered surface of the lug hole and rotate to engage lock mechanism with the lock bar groove.
