1h connector pin out

Does anyone know the function of the purple wire on pin 1 of connector 1h? This connector plugs directly into the body ecu. Thanks

 

3rd gen tacoma body ecu connector is M6. There is no information on pin 1

 

Ok, maybe I have it wrong. Connector 1h plugs ito the unit with the fuses under the left side of the dash. There is a purple wire in pin 1. I have attached a photo. There is also a black wire in pin 13 which is motorized seat power.

 

What year is this truck? I'll see if I can find it.

 

It’s a 2023 Tacoma access cab, 2.7l 4 cyl

 

Center High Mount Stop Light.

 

Beat me by a few seconds lol

 

Thanks very much everyone. I wanted to add the black wire for motorized seat power. To do this I swapped the lower half of 1h with one that had pin 13 and the wire that I got at a salvage yard. I then spliced the purple wire to the lead from the new connector. I just wanted to know what pin 1 did for safety reasons. Thanks again, and I need to give caribe makaira credit for the picture that I borrowed from one of his posts.
