Good wiring
It plugged right in after finding the stock plug placement. I routed it up from behind the kickplate, behind the e foot brake, up under the dash just tucked in, and through the back of the face cover of the middle console that pops into the cole under the radio. I modified that plate to make the brake box fit. It's all incognito and clears all the places I put it with no problems.

5.0 out of 5 stars Easy to install. Works as expected.
Reviewed in the United States on March 30, 2020

Since I didn't like the idea of anything protruding from under the dash where my legs are, or potentially kicking it while getting in and out, I decided to find a place to put the controller out of the way. After all, the chances of needing to access it after initial adjustments is pretty low. Thankfully, my 2013 Tundra has two glove boxes and the top one I didn't use all that much. To mount it in the glove box, I removed the whole thing from the dash and drilled 4 holes for the small bracket on the top. I then used two black zip ties to secure the unit to the inside of the glove box. Next I used a dremel tool to cut a rectangular hole through the back of the glove box for the wire harness plug. I may have got lucky in getting my snake to go right through the back of the dash from the glove box to the gas pedal. This allowed me to easily run the wire harness, which I cut and spliced to extend it. I hope you like this install as much as I do. I wish Amazon would let pictures be uploaded.

Perfect fit to factory harness despite Amazon telling me it would not. There is enough length in this harness to be able to mount brake controller on right side of steering column, and from my rough measuring, it will reach to a controller mounted in the small cubbyhole in front of the shift console on the dash. Perfect fit and perfect operation with the Tekonsha 90160 Primus IQ Electronic Brake Controller I used.

Worked perfectly on my 2007 Lexus GX470. Easy to install. Google the install to find pics on forums as you have to find the factory connector under the steering wheel column behind the panel. It’s easy to do, but you’ll need to be careful when cutting or breaking the tape from the factory to get it loose. End of the day it’s a 10 minute job at most and probably a 5 minute one if you’re a contortionist or shorter than 6’2”.

5.0 out of 5 stars Perfect Fit - not sure why the redunant ground is required
Reviewed in the United States on May 28, 2021

OK ordered the is for my 2013 Tundra w/ Tow package
Harness is plug and play with several Tekonsha controllers and maybe others (?)
found my white factory connector and plugged in the harness routed to the installed controller ( knee panel just below the rear window switch)

The harness is neatly wrapped in a sleeve as shown with the redundant white ground wire fully exposed from the controller connector........ I wrapped it in black tape about 8-10" from the connector to hide the white wire then routed it to a secured location ( brake pedal bracket) needed to open up the eyelet with a drill bit and then secure behind the factory nut.

Tie wrapped out of the way, looks factory.

Good Luck

4.0 out of 5 stars Works but it is almost too short.
Reviewed in the United States on March 29, 2022

Installing a Takonsha Primus IQ in my 2012 Tundra, this cable was almost too short and it took me awhile to get it to run via the most direct route possible. For a dash installation, the only place this would reach would be the top left part of the dash (in front of the defrost vent and speaker). Otherwise, it will have to be a knee-knocker somewhere on the lower part of the dash.
The cable is well made and the connectors fit perfectly - I just wish it was 6" longer.

Very easy plug and play once you know where the plug is. In the tacoma it is up under the dash to the left of the e brake taped woth other wires. Found it easier to take the kick board off the door and follow the wiring from the 7pin to the plug. Pain to get to, but the harness makes adding the brake control easy.

5.0 out of 5 stars Makes Installation of Controller a Breeze
Reviewed in Canada on September 7, 2021

I used this to connect a brake controller to my 2010 Toyota Tundra. Assuming you get the proper adapter for your vehicle, installation could hardly be simpler. Plug one end into the vehicle connector and the other into the controller. The trickiest part is finding a place to properly mount the ground wire. Once that's complete, DONE.
