All TechSmart headlight wiring harnesses are guaranteed to meet or exceed OE performance providing today's technician with the quality parts needed to get the job done right, the first time. Each TechSmart® High Temperature Headlight Wiring Harness features 14 gauge wire for better conductivity. Each TechSmart® High Temperature Headlight Wiring Harnesses a complete plug & play unit that plugs right in between the factory harness and new bulb for ease of installation. Each TechSmart® High Temperature Headlight Wiring Harness can be used as a complete harness or pigtail if the original connector is melted. TechSmart's F90015 high-temp design for H13 bulbs prevents the connector from melting when using high-intensity aftermarket light bulbs.
