I am wiring my driving lights up to one of my switches on my UPR Ash tray switch panel in my 87 GT. What size wire gauge should I use and what size fuse??
Right now I keep blowing 30amp fuses but I think the 14 gaguge wire is too small.
You should run those lights off of a relay. You size your fuse slightly higher than the current draw of the device. If the lights draw 9 amps, I would run no larger than a 15 amp fuse. For a motor, it is a little different. For a 9 amp draw motor I would run a slightly larger fuse for startup current. Wire gauge is dependent on the distance. A 10 gauge wire would work from a relay to the battery and to the lights. Might be too small if the bat is in the trunk!
