Ratchet
3/4″ Socket & Wrench
10mm Socket
16mm Socket

Removal

1. From underneath the driver’s side of the vehicle, unplug the main bumper harness connector. (Fig A)
Unplug the connector on the back side of your trailer plug. Then, remove the trailer plug from the OEM bumper by pressing in the tabs on the back side of the plug and pushing it out the front of the bumper. (Fig B)
Remove the two plastic clips that sit behind the license plate. (Fig C)
Under the license plate there is a bolt that needs to be removed under the cap that attaches the bumper to the hitch. (Fig D)
Remove Cap

Remove the Bolt
From underneath the vehicle, use a 16mm Socket to remove the two bumper mounting bolts (per side). Then, remove the OEM bumper from the vehicle. (Fig E)
Remove the two plastic clips referenced in (Fig F). Then, remove the module from the bumper.
Squeeze in the two metal tabs referenced in (Fig G). Then, remove that module from the bumper.
Remove the parking sensors from their mounting rings by spreading the two tabs on the back side of the mounting rings. Keep track of what position/orientation these come off the OEM bumper so you can install them on your new bumper in the same position/orientation. (Fig H) You do not need to remove the parking sensor mounting rings. You will not be reusing them.
Using a 10mm Socket, remove the bolt (one per side) that holds the license plate lights into place. Then, remove the license plate lights. Save these bolts for reuse. (Fig I)

Installation

Find the supplied set of four parking sensor bezels. Install these onto your bumper so that the skinnier part of the ring is facing upwards and the sensor connector is horizontal, facing the same direction it was on the OEM bumper. The inner two sensors have the connector facing towards the outside of the bumper, while the outer two sensors have the connector facing towards the center of the bumper. (Fig J)
Installations Instructions

You will need to first install the outer ring into the bumper from the front side. Then, snap the backer ring on from the back side. Finally, push the sensor into place from the back side.

Install the trailer plug into your new bumper by pressing it into its precut hole. If you trailer plug is loose, you can spread the tabs on the back side of the trailer plug outwards to help hold it in place. (Fig K)
Installations Instructions

Install your license plate lights. To do this, find the license plate light brackets. Then, install the license plate lights using the supplied brackets and the bolts that were set aside in Step 8. Install the license plate lights in the same position/orientation as they came off the OEM bumper. DO NOT OVER TIGHTEN THE MOUNTING BOLTS OR YOU WILL BREAK THE LIGHT HOUSINGS. Tighten the bolts until the lights aren’t loose anymore and stop. (Fig L)
Installations Instructions

Carry the harness over to your new bumper. Plug in the parking sensors and license plate lights. Also make sure the main connector is installed on the driver side of the bumper. (Fig M) As you install the harness, you can zip tie the modules from Steps 5 & 6 to the harness and let them hang.
Carry Harness

If you have cube lights to install on the bumper, do so now. Follow the light manufacturer’s guide for mounting/wiring information.

If you have a retracting bed step on your TRX, follow this step. Otherwise, skip ahead to the next step. Remove the felt pad that acts as the stop for the retracting step. Then, install one of the supplied rubber grommets and reinstall the pad. You may have to use some RTV or something similar to hold the felt pad in place. (Fig N)
Wiring Information

Set the bumper in place on the vehicle. Then, loosely install the supplied 1/2″ Bolts (2 per side), 1/2″ Washers (4 per side), and 1/2″ Lock Nuts (2 per side). Leave these bolts loose for now. (Fig O)
