Go straight to the battery, your fuse block won't handle it. Well it could but you'd have to up one of the original fuses you rob it off of. There is an accesory plug but that runs off the dome light circut. I would run a direct lead off the battery. I took an 8 gauge wire ran it to the battery and fused it at the end with a 30 amp fuse. Then I ran through some of that plastic tubing into my firewall. Just pop out the plug where the spedometer cable goes and run the cables through their and use a bushing around the hole (may not be the best if you go through deep water but it works great for me). Then I ran the lead to my switches inside the cab (each switch is also fused with 20 amp fuses). The wires going to my lights from the switches are hidden behind my door trim and pop up by the hard top. I cracked the hard top and ran the wires through the gap and closed it. I used a little black silicone to keep out moisture. Its a good fit for 12 gauge wire but anything bigger might be trouble. I also run my CB from the power lead running into the cab so thus the overkill in wiring. All totaled it runs the CB, and 4 150W KC Daylighters and the power lead runs as cool as cucumber. Its funny to listen to my engine at idle when I turn the lights on, she drags a little cause of the stock altenatot.
