    Hoping I can get some help on a few items as I ready for towing. I'm looking for: 1) clear pictures and directions for getting at my brake controller harness; 2) how your Tekonsha P3 is mounted; and 3) recommended clip on or other types of towing mirrors you use.
    Thanks!

    I have the tow package and P3 installed in the cubby located to the left of the steering wheel. I made my own modifications to the pocket, but in hind sight it would have been much easier to just buy the cubby linked below (screws into the back of panel so you can keep the factory unit for reinstallation at a later date, if needed.) Behind the drivers side kick panel, and buried under some wires is a pig tail you can connect to your wiring harness. It will allow the P3 to connect to the truck without splicing any wires.

    You can mount the P3 with the supplied mount, but I have long legs and anywhere under the dash was pretty much a no go due to space constraints. I did not want to be bumping it with my knees on a regular basis.

    This is the harness I used:

    You can also use this mounting plate to conveniently mount the P3 to the dash. It is worth the investment in my opinion.

    Thought I'd report out on how it went. I ordered the P3 and the 3017-P harness from Amazon and the mounting kit from ESP Truck. ESP shipped immediately - outstanding! When it all arrived, I tried the fit of the P3 into the ESP bracket - uh-oh, it appears to catch on the top tab of the P3...doesn't look like it wants to go as far as it should. The harness on label says for 2015 Tundra - uh-oh. Anyway, head out this morning to install it and see what happens. The door sill plate snaps off just fine, then onto the side panel. There are 3 points of connection. Remove the visible screw, then the top connector pops off towards the center of the vehicle and the bottom one slides out towards the back of the vehicle - they are two very different type of connectors. So correct order is screw, pop top towards center of truck, pull panel towards back of truck. Reverse putting it back together. The plug is quite visible and easy to find once that panel is off. Take off the 3 bolts at bottom of the dash panel then pull straight out - there are about 8 red snap connectors that hold it on. The ESP instructions said to take off the switch panel but I didn't bother - I could still easily get at the screws to take off the cubbie box. On went the ESP bracket, in went the P3 and although there was a bit of tension, the 2 supplied screws went in. Rock solid feel. Harness clicked in and ready to put panels back. Two things to keep in mind...the panel went back together well when I snapped in the right hand side first. I had started with left but the right hand was more finicky so I pulled it off and tried again. Second thing, one of the red connectors fell off and the side plastic piece holding it bent when I tried to snap it in. So basically I re-bent it properly, carefully held the loose red connector in, started and worked right to left. Boom - looks great. Then on went the kick panel and the sill. Everything connected and back together. Looks awesome and out of the way of my knee. Highly recommend ESP's plate for a clean professional look.

    P.S. - I'll fess up...I put the f#%& plate on upside down! Yup, no wonder it was a tight fit! Lesson learned - pay attention to the details! A real Homer moment when I realized it. Nope, not changing it - it still works. Photos:
