I believe this wire (hot) comes straight from the 20 amp fuse marked "Working Light" on the fuse box cover, not from the switch. Mine was wrapped up in black electrical tape behind the seat, over the 3ph. There are actually 2 bullet style connectors, one male (ground) and one female (+). I have four 55 watt lights running off mine which will be in the neighborhood of 15.2 amps to 17.6, depending on whether the engine is running or not. Hope this helps.
