Upon doing a few digging online, a long phone call with Chris from Toyota and some help from a trusted friend. The door pin switch which works with the dome light, that communicate with BCM is apart of the door latch itself. My 4th Tacoma came with no bed light, so I’ve been trying to find a clean solution same as OEM. There is a purple wire that grounds the latch switch that tells the dome light to come on when it’s open.. if you connect led to a constant power and negative to purple wire to a tailgate pin switch. Lights works as a dome light..

I've read online that it is normal for the back seat of your truck to warm up because of the battery. Well, that's not really the case and wanted to share a simple tip for it.

I found out that if you put the heat and cooling system on the floor blowing mode, it helps to reduce the heat for the rear seat of your truck.

I know Tacos have a vent for the rear passengers under the front seats. Which can be used to control the temperature back there. Figured this would be a useful tip for anyone who might be facing such.
