I have 4 Interior Light tubes that I want to hook up, problem is the fuse(or so I think) is blown in my cig lighter outlet, so theres no where to hook the 12V adapter into. What would be the best place to tap into to run my lights?

Uhh. Wouldn't it be easiest to just change the fuse?

1) uh, replace the fuse
2) tap into the wires on the back of the cig lighter so you don't lose your only 12v outlet.
3) ?????
4) Profit!

Depends if you want them always on, only when key turned or when door is open.
If you want them always on, tap into cigligter fuse.
If you want them on when the key is turned, tap in to radio fuse.
If you want them on when door is open, tap into +12v and for - tap into the dome light (I don't know any other place)
If you want them on when you turn parking lights on, then tap into the lights fuse.
