2024 Tacoma adding trailer brake controller OEM or aftermarket ??

This one is a done deal, all Taco have it. Fuse Block with multiple terminals.

If Taco has the J7 OEM Trailer Brake Control ECU, Redarc can tap these wires.

 

Instructions??

 

Where behind the dash is the J7? Right side, left side?
Would I have to run wires to through the cab to the battery too?

 

Left side of steering.
No wires to run, if you have the J7, those are the wires required to tap into.

 

Right. Yeah. Makes sense if I have the J7. Not sure how to tap into that ECU

 

You'd tap into the wires, not to a ghost ECU.

 

Hey! What do I know?!!

 

Did you ever find a resolution? I am so frustrated Toyota would do this and agree can’t believe I have to old school hard wire my Tekonsha controller. I hope they get enough complaints that they offer the option to install.

 

Did you ever get this resolved? I’m trying to verify that this works and there are no issues with other sensors etc on the truck. It would not be fun to buy a 2024 SR5 without the factory controller and find out later I can’t get the red arc to install properly. The packages that include the factory controller are expensive and have a bunch of other stuff I don’t necessarily need.

 

I went to my local trailer place. They said they can find the correct wiring harness to hook up my Tekonsha Prodigy P3. From what I understand it’s not exactly a simple plug in situation but they also don’t have to run wiring from the 7way to the battery, etc.
Hope this makes sense. There seems to be a lack of information out there and Toyota is of no help. Again, why install a 7way and tow package with no way to hook up brakes?‍♀️

 

Because you can still tow trailers that don't have brakes, I suppose?

 

True. I certainly can do that. But once my weight in the TV and camper are over 2k I want brakes!!

 

It's a big TV?

 

No. It’s only 1000lbs. But between dogs, 2 adults and our gear, we’re at about $1800. Still weigh below tow capacity of 6640lbs. If we for a bigger camper or went to mountainous states I’d want extra protection.

 

Hi, I just got the 2024 Tacoma off Road yesterday...mine came equipped with the brake controller...on the dashboard, to the right of the steering wheel, it has a + and - plus a slide lever...

I don't mean to be thick, but did yours not have one?

 

Hi 3rd Gen owner here. I am kicking tires on a 2025.

My 3rd Gen trim is SR5 and it came fully equipped to tow from the factory (brake controller harness, 4 and 7 pin plugs mounted in rear bumper, tow hitch, aux. transmission cooler (no longer provided, it was dropped mid 3rd Gen)). I only needed to add my brake controller of choice and connect to the factory provided harness conveniently tucked behind the kick panel. It was simple.

When I shop on the Toyota site, I see only some 2025 trims have a factory brake controller which I do like. Furthermore after reading this thread I see it is not as clean as it used to be to add a brake controller to a vehicle not equipped with one, it seems the harness doesn't exist even though the hitch and 4/7 pin plugs may be installed. My question is; what are all the trim levels that have the complete ready to go package (Toyota brake controller, 2" hitch, 4 and 7 pin plugs)? The Toyota site is not helpful, you have to open each trim and scroll through the features to find "brake controller". I could not find a matrix showing trim versus brake controller availability.

Thanks.

 

All dependent on the trim/package you get.

 

@Sizzlemonkey We have an SR. Comes with 7 way and tow package but no factory brake controller. As stated in a previous reply, my local trailer place said they have a work around and can do it. No under dash harness though. Crazy.

 

Hey y'all, just wondering if there has been any updates on this issue or any news on whether the 2025 TRD OR trims might have gotten better? Here in Canada keeping the (useful) OR trim goodies but getting a factory brake controller requires the "Premium" package which gets rid of the 6" bed (not an option for us) and adds another 8K CAD of stuff I don't need or want....

 

Haven’t heard anything new. And, from what I know it’s the same situation here in the US as you describe in Canada. Been said before but just crazy that the brake controller isn’t even an option on the models without it. Who ever heard of selling a truck with a “tow package” that had no easy ability to add a brake controller!
