2024 Tacoma3rd brake light feed

Thanks, I looked closer at the FBC site and found the pig tail that taps off for the 3rd brake light.
This thread was the only successful search - here is what I ordered https://fbchs.square.site/product/tacoma-2016-2023-brake-t-harness/47?cs=true&cst=custom - just the plain $30.00 connector
Thanks for your help

 

Purely FYi for anyone else, this is the third gen brake T thread:

Problem with turn circuit on 2024 is that they behave like the towing turn & stop circuit.
B = Backup/Reverse
TRN = Turn
TL- Tail/Parking
E= Ground

 

Stop Circuit:

Notice that the Combination meter assembly mixes the turn & stop to rear combination lamps. Only Center Stop light assembly is isolated.

 

I got those chmsl connectors ready, just need a willing tester to be game to drop the headliner for a clean brake and cargo T

 

Any update on a topper stop light T harness for the 2024 Taco?

 

What update do you desire?

I’ve done taillight T harness pairs for one guy who did a module to extract a brake signal from the combined stop + turn on each side. Kind of a hassle.

Then I have connectors for a cab 3rd brake light T which is an easier path but requires dropping the headliner and then routing wire from cab to bed. I need someone willing to test and prove that solution like @brhodea did for 3.0 Gen Tundra here:

Gotcha. Honestly, for whatever reason, dropping the headliner seems scary to me. So If I understand correctly, the headliner route is an easy T harness, but the taillight route is a more difficult module to create? For the headliner route, I guess you'd go down under the floor through a rubber gromet and then under the truck to the bed and then up through the taillight assembly and into the topper?

 

Is it the same headliner T for the hybrids? I'll test it for you if so.

 

Your call. $50k for a midsize pickup truck is what scares me, though I have about that into my POS '16 so I'm the real idiot

Taillight requires a module, not sure if that incurs a delay (talk to the guy above who did that) so hard for me to speculate on pros/cons without having a '24 to tinker with and a spare day, neither of which is at my door right now.

For routing from cab to bed, you'd supply your own wire and have to deal with that but you do get cargo for free which is more value to Tundra people without OEM bed lights, I assume '24's have the 3rd gen bed light stuff?

No reason to believe it's different but I've only caressed a 4th gen, never took it's clothes off...

 

Ha! I do have bed and scene lights in my Trailhunter. I'm willing to give it a shot if you'd like me to test it out.

 

Ok, so, step 1 is confirm wire colors and connector are a match to this spec. If so I can send you a T w 60" leads and you can button it up and test it out. So, drop headliner enough to visually inspect and grab a photo showing wire colors and connector.

Medium Blue == This should be the brake signal. You don't really have to probe this but we want to confirm it's in the middle spot aka the 2 spot.
White w black stripe == ground. This should be in the 1 spot so one of the outer positions.
Light Green == This should be the cargo light signal. Again you don't have to probe this to confirm but it should be on the outside in the 3 spot.

Technically these signals do exist in the driver kick panel as well but they are together with a lot of other stuff so much harder to identify and I don't have the connectors for any of that right now. If you want to muck around there you'll need to probe and take photos and count positions in the connector and be super clear and then maybe I try to find connectors but sometimes those are super difficult to source.

You're effectively proving my theory before I send you something and proving you know how to take the headliner down without breaking your truck. Should be easier the 2nd time and you don't have to buckle it up tight if you don't want to. Follow the general steps here, noting that is a Tundra so an entirely different truck. Take your time and stop before doing anything you aren't sure of and ask questions, nice new truck so don't snap a piece of plastic trim by mistake.

Looks like some nice options for 4th gen here:
