what is this? how do i wire a 12v plug?

I pulled up my cup holder (man trans) and i found this wiring harnes going to nothing. What is it? I want to wire a 12v plug in my cup holder. How would i do that? im cheap and dont want to buy car chargers for my camera, cell phone, ect so id rather just put a plug in my truck seeing as i didnt get the trd

 

there should be some way to install one without an inverter no?

 

Ill try splicing it. That's a good idea

 

I dont have a 2nd gen, so I may be mistaken, but I'm pretty sure that they'll also be a fuse that is missing for those with out the inverter installed. So, before you check voltage, make sure you have a fuse in as well. A 15A is pretty standard for cig lighters and should be rated under the power draw of what the inverter could do (400W?).

Also, since there is a toggle switch of sorts for the inverter (not sure if its a on/low/high, or if its just low/high), you may have issues getting power to that connector because of that as well.

If its just a very low amp, I think I'd just do like whippersnapper suggested and tap into the existing cig lighter. If higher amps are needed, I'd run a new wire for it with its own dedicated fuse.
