The switched and unswitched accessory circuits cannot handle 15 amps! They are only 20 gauge wire. The maximum amperage at 12 volts that this wire will handle, running alone, in 70 degree air, is 11 amps. Running in a bundle, in the heat under the Tupperware of a Spyder, or for any distance beyond three feet total (power + ground), will reduce the ampacity. The greater the current draw, the more the voltage will drop, also. I think you could sneak by with more than the standard 3 amp rating for this wire size, but I certainly wouldn't count on anything over 5 being reliable, and a substantial draw could be unsafe...and cause a fire. JMHO.

I agree with Scotty on this one. You may be able to run 15 amps on that circuit for a while but you are asking for trouble if you continually push it over what the wires and connectors are rated for.
