2014+ Toyota Tundra 5.7.

Looking to install a brake controller. Toyota LC connection is 5 wires, all the controller units are 4, ??? How to combine 5 to 4. I've chosen the "tow pro elite" to install. It has many advantages and the very small controller is perfect and un intrusive.

Isn't there a plug on the left side of the kick panel with a plug you wire into? The controllers I bought had a matching lug with wire instructions included. Does your control have a plug and instructions?

in the Tundras i have had there is a loose pigtail wire that comes with the truck, i think in the glove box, that my
controller then plugged right into, as sixdogs said down under that access panel to the left the driver's feet.
i use the tekonsha P3 controller, and have moved it from truck to truck 3 times...

The pig tail did come, it has five wires, all the brake controller units have four. That particular unit you have the tekotonsha supplies a five/four connection.

Look in the instructions. Mine was a 5/4 thing too and I don't remember what the answer was but it took all of a minute to figure it out. Look online if no instructions and if you can't find anything I'll walk out to the barn and see if I still have the instructions.

from a 2016 tacoma discussion:
Since REDARC does not make plug & play wiring harnesses I purchased a Tekonsha Trailer Brake Control Wiring Harness 3017-P that plugs right in to the factory connector behind the kick panel which was pretty easy to locate. I cut the wires on both harnesses to stagger the connections then soldiered them, wrapped them individually with electric tape then all four with some friction tape and finally put some split loom over the entire length. This will leave plenty of slack for the installation, enough that I made a loop and zip tied it to a dash bracket just left of the steering column after getting everything positioned.

What functions​ are different between the 4 wire and 5 wire pigtails? Is one perhaps for a dashboard light or something?
You should have:
1. Power in
2. Brake signal in
3. Modulated power out to the trailer brakes
4. Ground

As long as your truck has those 4 outputs to match the controller input, who cares what the 5th pin is for.

Ok Tundra owners, looking for reviews on the 2014 to present Tundra Double Cab 5.7 4x4. Love my 2011 Sierra 4.8 but will not be buying another 1500 from the General. I want nothing to do with AFM or EPS and don't need a 2500HD. Toyota does not use either AFM or EPS, and that is huge in my eyes. I love the 4:30 gearing 5.7 combo too.

Pics and reviews welcome.

Can't speak for the 2014 and newer but between my brothers and I, we owned Tundra Double Cab 5.7 2004 (350k miles), 2005 (300k miles), 2006 (mine 200k miles). There are no plan to replace them anytime soon.
Among the things we have learned:
* The starter is a beotch to replace but only the 2005 one failed because it was flooded.
* I don't care what Toyota says about sealed transmission and to not worry about the fluid. Drain and fill at first 60k and every 20k miles afterward is recommended.
* Toyota says don't change spark plugs until 100k and you can believe that. I changed mine at 150k and they still looked pretty good.
* Change the water pump when you change the timing belt if you want to save yourself some hassle.
* The Tundra got a turning radius of an 18 wheeler! It's always a struggle fitting in a parking spot, most particularly at my local Lowe's hardware store parking lot.
* If you rock back and forth hard between Forward & Reverse to get unstuck you may twist the Universal Joint off your drive shaft. When that happens, don't go to the dealer for a replacement. They want $900 for that precious piece of pipe. Find a machine shop that will weld that thing back and balance it for you. That will save you $700.

Other than that things are all good. Right now my brothers and I are targeting 500k before thinking about replacement. I used to want a diesel because they last a long time. These new gas engines are making me change my mind.

BTW, I'm not at all bashing any other cars or trucks. For all I know they are all good nowadays. The Tundra met my needs and I'm sticking with it.

My 2007 Tundra with the 5.7 does not have a dipstick for checking tranny fluid level. Dealer told me you have to check on side of tranny. Mfg wanted to prevent oil and tranny fluids mixed together, hence only one dipstick for engine oil.

Do the drain and fill at first 60k and then every 20k. It's dead simple. You can find instructions on YouTube. For me, I just drain and measure what I took out. Then I undo the hose at the transmission oil cooler and use a $6 pump I bought at HarborFreight to pump the fluid back in the transmission. Then I run the engine until warm and open the overfill plug at the bottom of the pan and let the extra fluid out and I'm done.

I believe that the transmission is sealed, and serviceable by the dealer only.

If I remember correctly, I think I saw on the tundra forums years ago that the transmission was not supposed to be serviced until 150000 miles

Don't believe that! If you tow and drive hard, the transmission fluid will degrade. Do the drain and fill. Each time that will only replace roughly 40% of the fluid. There is no need to pay big bucks for the flush.
