Trailhunter lightbar add research

@jay_zed PM'd moi for info on the Trailhunter "OEM" lightbar wiring so he may add it to his Taco. Seems it's way too new to find info on it. Adding it to a non-Trailhunter might be easy, except for the tie in to CAN BUS. (maybe) But I have some wiring details:
Switch location

Fog(s) circuit:


Fog Harness:


Trailhunter switch:

 

FYI from factory, lightbar only turns on with high beams on. If high beams are not on, pressing light bar button will cause it to flash twice and shut off.

 

Hense the can-bus comms. Working on how to have same functionality without can-bus/techstream massaging.

Does your Taco have the light bar? Luv to see switch connector and wires to it.

 

Thanks @caribe makaira for digging up the diagram!

Yes, I saw in the review videos that light bar is tied to the high beam. If I understand the diagram above correctly, this is probably the purpose of the tie-in to the left headlamp assembly (lower left corner of diagram).

 

That would be the reason for fogs off at high beams...

 

LED Beam Fuse (HEV)

 

Light bar and fog light buttons share the same module:


Connector end:


Connector wiring:


Lamp connector at the grill:


Will wait a few hours for further requests before buttoning back up.

 

@snickers , You have picture of light bar connector mating view?

Also, other side of switch connector to view wire colors.


Are you able to see/trace where the cable loom mates to on the light bar? Seems it runs down the grill...

 

Loom from lightbar runs down, joins loom from front camera. Not sure, but also think loom from radar joins further down. It then runs passenger side and up to this junction left side connector and then right side goes down and appears to go toward passenger side fuse box.


There are not many viewing windows and my hands don't fit through gaps to follow by feel.

 

Connector houses Millimeter Wave Radar Sensor wires and front bumper parking sensors harness.

 

Oops lost tracking somewhere. I will have the grill off when I have a front bumper put in a few weeks. If, interested I can take photos.

 

Please do.

 

If one really requires an added LED Bar to be on only when High Beams are ON, this can be done:
