Good news everyone! If ya get a good enough switch, you don't have to run a relay.
120W on 12V draws 10A, something that is a stretch for 18ga wire but within tolerance of 16ga and certainly safe on 14ga, still a decently small wire. Cheap 15A switches, in my personal experience, will kerplode about a year in on a 10A circuit. I would get a 20A or fancy 15A switch if I wanted to avoid a relay, but you can go that route.
That said, personally I'd hook a 14ga wire to battery (or pdc) and run it fused to the 30 post, then from 87 post to the lights. Ground the lights (still 14ga). Then run a 20-22ga wire tapped from an available circuit (remember, we are talking well <1A on this wire) or battery/pdc (fused) and run it to the switch, then on to post 85. Ground the relay, post 86. Easy as Sunday mornin. Some parts stores (and amazon) sell relay harnesses that make it splice the wire, plug & play, as opposed to spade terminals on each wire.

How big (wattage and quantity) are the lights (or cumulative wattage of the bar)?

|BlueRidgeYJ||Yea, you'd need two power leads, a low amperage relay trigger (from just about anywhere) and a primary cable (from a direct source) for the lights. Make sure your fuses/wires are appropriate for the lights amp draw.|

|unlimitedsoldier||Ok, with that wire diagram do I have to run my power from the battery and fuse box or and I use either or?|

Switch to relay wire diagram
Hey guys and gals, Im in the process of trying to wire a light bar to my TJ and have never done a wire job for this. I am wanting to add a switch to the inside of my Jeep so that I can turn it on and off when ever I want. I have tried to find diagrams on Google but have not found anything that really showed much.
I was told that I have to run a relay for this kind of job, have a sorta idea of what I need to do but does anyone have a diagram that they can post here of anyone have any advice?
Any help would be appreciated.
