Check to make sure nothing is in the way. (This customer has a relay holder mounted right where the PowerTray mounts; This relay will no longer be needed as their light bar can now be wired directly to the Switch-Pros.)

Pro tip: Remove the factory fuse box cover so you have more room to get a hand under the PowerTray. You can also angle the PowerTray up and rotate it for better access on the first bolt.

Hold the PowerTray with your right hand and use your left hand to begin threading the M8 flange bolts into the factory threaded holes. Continue to hand tighten the first bolt until snug. For the second bolt, slide the PowerTray back (towards the cab) and the factory threaded hole will be right below the front edge of the PowerTray. Again, install the bolt until snug. We'll come back to finish tightening these after the PowerTray is positioned exactly where we want it.

Attach the support leg to the inside lip on the PowerTray with the included M6 hardware. Tighten until snug. 

The bottom of the support leg attaches to a factory bolt that holds a bracket for the front differential breather lines (Two black tubes with silver caps). First remove the bolt, then add the support leg and reinstall the bolt until snug. It should be assembled in the following order: Bolt > Support Leg > Bracket > Fender.

Final Step: All the hardware should now be snugly installed. First slide the tray forward/backwards until its spaced evenly between the factory fuse box and master cylinder. Then use a small 1/4" drive ratchet with a 12mm socket to finish tightening the two M8 flange bolts on the fender side.

Its a little tight under the PowerTray, so just take your time on this step. If your big beef-cake arms just cant get this step done then some folks have found it easier to use a combination of extensions/swivel sockets in order to bring the ratchets handle out past the edge of the PowerTray.

Make sure the support leg is straight up and down and not angled. Then use a 10MM ratchet or wrench to finish tightening the connection at the top of the support leg. Note: The serrations on the M6 flange nut will bite into the aluminum support leg when you tighten the bolt. Simply hold the nut firmly in your fingers while you tighten the bolt and let science do the rest.

The lower support leg is the last connection we need to address. before tightening make sure the PowerTray is level. Pro tip: reinstall the factory fuse box cover for a level reference. The surface of the fuse box cover should run parallel to the surface of the PowerTray.
