The harness will work with any 99-07 GMC or Chevrolet truck of this type (GMT800 chassis). The base harness has three 3157 jumpers. Two go to the driver's side (Park/Turn bulb and DRL), the other goes to the passenger side Park/Turn bulb. Jumpers allow you to continue to run your stock DRL and park/turn signal bulbs. VERY IMPORTANT: USE THE INCLUDED DIELECTRIC GREASE IN YOUR STOCK SOCKETS. IF YOU DO NOT, THE CONTACTS WILL CORRODE AND THE BAR WILL STOP WORKING. THIS IS NOT COVERED UNDER WARRANTY. That's it! No cutting, no soldering, no crimping, no modification to your stock wiring, whatsoever. What's even better? We have integrated HD Load resistors. This will allow you to run LED turn signal bulbs without the effects of hyperflash. It really couldn't get any better. Still have questions?
