Brake controller harness for 4th gen Tacoma?

[geonerdist]

I have the same truck as you with the heated seats and lg screen but no brake controller. What redarc model did you order and can you explain how/where you wired the controller? Is it powered behind the rear passenger seat? How did you run the wire to the control knob in the dash?

I've been meaning to post my write up and kept forgetting. Thank you for the reminder. See attached document.

Thanks for the write up. I’m picking up my trailer this week and will probably drive it home 40 miles without trailer brakes. I hope the 7 pin connector on the taco at least has brakes lights connected for the drive home. I will start on this asap.

Mine did so wishing you the same luck.

Thank you for all your hard work putting that together.
It helped immensely when buying the truck as I raised the issue of no brake controller option with dealership and they couldn't figure a simple fix. Redarc shared your pdf step by step with me and I then with local Action Truck and Trailer shop.
Because dealership couldn't find a way to add the oem brake controller, they agreed to have local shop install Redarc and have it all on bill of sale so I wouldn't have warranty worries.
Made the situation straightforward and a big thanks to you for making that painless.

Thanks for the write up and all the time and research that went into figuring it out. I just completed installing my TowPro controller and came up with a few ways to save some cost and simplify the installation. Take a look at the attached document and perhaps you might want to update yours. Otherwise for all, here are my suggestions.

Great find on that blew wire! I had a feeling that was it but I didn't have the right tool or a friend at the time that could help me check continuity on that wire.

If you have a blue wire in the position on the 7-pin harness in the back, it does go inside the cab under the passenger side back seat. So no need for running a new one like I did.

It seems the signal wire could be traced to up front somewhere and eliminate the need to cut into the harness.

Wireless option..

I read reviews about the Curt Echo on Amazon; connection issues are common so not a great choice.

Wow! Excellent instructions. I know I’d never do this but I guess I could give it to a local shop.

I’m a little confused…Etrailer suggests this controller:
Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness - Dash Knob - Proportional
Part Number: RED52VR

the website says the ProElite doesn’t fit the ‘24???

Thanks you guys for the writeups. Do those instructions also apply to the 2024 SR Manual? If I understand the previous posts correctly, the SR probably lacks a pin on the 7 pin harness, but the Off-Road does have all pins?

My Off-road had the 7th pin. But I don't think we have ever figured out a method to Toyota's madness on this topic. My educated guess would be the SR would not have that 7th pin.

Our ‘24 SR has all 7 pins. I’ve traced the brake wire into the cab so it’s there!

Is it still possible there is a hidden harness for the OEM controller? They sell the switch for it so maybe . We need someone to dig into a wrecked one and find that harness. Or experiment with one. I’m thinking there must be a way to wire in the OEM unit.
