I switched my outer auxiliary lights to run off the Fog Light circuit. It's fused for 10A, so you can only run one set of lights off that circuit. if you switched to all LEDs, you might get by using that circuit for all 4 original lights, but you'd still be cuttings things close. I simply changed my fog light connectors for something that would hook up to the auxiliary lights connectors and used the Slingshot only switch kit..
