I have used up upfitter 1 and 2 for cube lights. #3 says 15 amp. I have a 20 amp light bar to install and want to use # 3. Can I put in a 20 amp mini blade and be ok?
Use up fitter 1or 2. You can upgrade the fuses on 1&2 to 40 amp even though they're 30amp from ford. The wiring is maxed at 40amps though on 1&2. The wiring for switch 3&4 are already maxed with the wiring size stock.
I have my up fitters like this:
30" behind grill with 2dually white spots on switch 1
40" behind grill with Hood mounted light cannons on switch 2
Amber rings and amber 2duallys on switch 4
Rear TMX bed mounted green rigid dually's on switch 3. I'll be using all my rear mount lights in the future on switch 3
I'll be using switch 1 again for my lightrack mounted LEDs with upgraded fuse to 40 amp at a later date.
