Circuit Performance Heavy Duty Wiring Harnesses are designed to install easily to protect your wiring from the additional heat generated by aftermarket upgrade bulbs.Q: Do I have to modify my factory wiring? A: No. Circuit Performance harnesses are a plug-n-play design which means the harness acts as a little extension cord and simply snaps in between your stock socket and the bulb. The harness can be installed or removed within seconds, great for leased vehicles! Q: Do I need to replace all of my factory wiring?A: No. The heat generated by high performance bulbs is isolated near the base of the bulb. Circuit Performance harnesses are made of a material that is designed to withstand that heat. As long as the rest of the vehicle’s wiring is properly fused, no other upgrades should be necessary. Q: My aftermarket bulb is stock wattage, would you still recommend upgrading the harness?A: Yes! It’s always a good idea to upgrade your harness when installing any aftermarket bulb, because whether you’re turbocharging your motor, or improving light output, nothing is ever as safe as your stock equipment. Q: Why should I choose Circuit Performance harnesses over another brand?A: Circuit Performance harnesses are made to a much higher quality standard than other aftermarket harnesses. Circuit Performance uses a ceramic base that plugs onto the bulb while other brands still use plastic. The ceramic connector resists heat to a much higher temperature than any plastic connector. Circuit Performance harnesses also use the thickest gauge wire possible for each application (14GA in most applications). Q: Will this harness fit my vehicle? A: Circuit Performance 9004 Heavy Duty Harnesses will work in any vehicle where an 9004 bulb is used.
