**NOTE: If you have a 2020+ 4Runner you will first need to relocate a small relay box prior to installation. CLICK HERE to see how.
Step 1: Bolt the PowerTray to the Inner Fender.
Remove your fuse box cover to give you more room for your hand. Start with the back bolt closest to the firewall. Angle the tray up while you begin threading the M8 flange bolt by hand.
Now rotate the tray down so you can install the forward most M8 fender bolt. (Tip: You can keep the tray tilted up for more hand room.)
Finally center the PowerTray between the factory fuse block and master cylinder. Use a small ratchet with 12 mm socket to finish tightening the two fender bolts.
Step 2: Bolt the top of the support leg to the inside lip on the PowerTray.
Note: The support leg has a top and a bottom. The smaller hole at the top attaches to the PowerTray and the elongated hole (on the bottom of the support leg) gets bolted to the lower fender.
It looks cleanest when you attach the support leg to the inside of the bend. Also, put the bolt in from the engine side so the serrated flange nut is on the underside of the tray. Next we'll attach the bottom before fully tightening.
Step 3: Bolt the Support Leg to the Lower Fender.
The elongated hole on the bottom of the support leg will be attached to a preexisting hole on the lower inner fender. This area is best accessed from the wheel well.
Now with the support leg in place, go back up to the top connection. Make sure the support leg is vertical by sliding it forwards/backwards. Then use a 10mm wrench and fully tighten the bolt. The serrations on the flange nut will bite into the aluminum so you don't have to use a wrench on the underside of the tray.
Lastly you want to finish tightening the bottom of the support leg. But before you do, make sure the tray is level by sliding it up and down. (Tip: Put your fuse block cover back on and use its edge as a parallel reference.) Again, the serrated flange nut will bite into the support leg as you tighten, so you can just tighten it from the wheel well.
