Best quality, hand built in USA Headlight Harness. 14ga SXL wiring Ceramic H4/9003 Headlight Sockets We saw all the headlight harnesses being offered, and we knew we could do better…and we did! We’re using automotive grade SXL wire (think Mercedes or BMW quality) and ceramic headlight sockets (for maximum heat resistance from high-output bulbs). The lengths are wrapped in high-temp split loom for heat and abrasion resistance. This complete package allows your headlights to receive the maximum amperage for the maximum light output! For Jeep Wrangler YJ (1986–1995) owners, this upgrade helps deliver brighter, more consistent headlight performance by reducing voltage drop and improving power flow to the lighting system. NEW! We modified our headlight harness to have the factory fog light connection. The small pig tail wire coming off the driver's side relay harness connection will connect to the small red wire on your factory (97-01 only) harness. This fixes the problem of the high beams turning on but not shutting off. If you don't have factory fog lights, no problem just secure the pig tail with a little electrical tape and you're good to go.
