P3 Brake Controller & Harness were delivered from Amazon. Even came with the controller wiring harness that plugs directly into the stock OEM harness plug. No cutting or splicing of wires required. A high quality product - best brake controller on the market in my book.

P3 Brake Controller Mounting Kit was also delivered from ESP Truck Accessories. Another quality OEM product from Toyota and modified by ESP. Allows you to mount the Prodigy P3 in the dash of 2014, 2015 & 2016 Tundra Trucks! Clean easy install without cutting dash. Easier access to your trailer brake controller without leg interference.

Please read this WARNING before beginning any work.

Installing Brake Controller Mounting Plate part# TP#MNT from ESP Truck Accessories and Tekonsha P3 Brake Controller with Harness from Amazon.

Tekonsha P3 Brake Controller includes generic wiring harness, instruction booklet/sheet, three mounting brackets, assorted screws, four wire connectors, and a nice carry pouch.
(Aftermarket wiring harness with P3 plug on one end and OEM brake controller factory wiring plug with ground on other end was included with Amazon purchase combo.)
P3 Trailer Brake Controller Mounting Kit comes with Dash Trim Plate, Instruction Sheet with some tiny pictures, and two controller allen head mounting screws.

As with any install - read entire instructions from start to finish. When you have a good mental picture you are ready to install:
1: Remove driver side sill plate by pulling up. Be careful not to break any plastic tabs.
2: Remove driver side kick plate by unscrewing plastic nut and sliding plate rearwards. Again, be careful not to break the two plastic slide tabs.
3: Remove the two 10mm bolts that are holding the lower dash panel and carefully pull outwards. Start with the bottom section of panel then top. Yet again, be careful not to break any plastic tabs or pull wiring.
4: Remove the right side upper dash trim plate by pulling outwards then unplug trac off & tow/haul switches.
5: Remove switches from original plate and snap into P3 Mounting Plate. Make sure you put switches back into the same locations.
6: Push the P3 Brake Controller into front side of P3 Mounting Plate and install the provided 2 screws into original mounting holes in P3 Brake Controller. These two screws secures brake controller in panel.
7: Plug in wiring harness (black flat plug) to rear of P3 Brake Controller. Route the wiring plug harness over to the kick panel side of vehicle. Plug in the trac off & tow/haul switch plugs.
8: Reinstall the P3 upper dash trim plate by aligning the four tabs and pushing plate inward until it snaps in place.
9: Locate pre-wired brake controller wire plug in kick panel area. Mine was hiding - electrical taped to side wire harness bundle. Untape it, plug in other end of brake controller harness (white square plug).

10: Reinstall lower dash panel and both 10mm bolts. Do not over tighten.
11: Loosen ground wire bolt to left of parking brake and attach ground wire.
12: Reinstall kick panel w/plastic nut - finger tighten only.
13: Reinstall side sill plate.

Note: Set up P3 Brake Controller by following manufacturer instructions.

That's it! Easy install.

If you ever decide to sell your truck and want to keep the controller for your new vehicle - no problem. Go through the steps again to disconnect & remove wiring harness then reinstall original panel & switches. You are now back to stock.
