03-07 GMC & Chevy Truck DRL Grille Bar Harness - Harness Only

SAVE YOURSELF HOURS OF WORK!!! 

Here at Sparksmith, we are looking to expand the line of bolt on lighting accessories available for the GMT800 chassis trucks. One way to do that is with plug and play wiring harness. The harness will work with any 99-07 GMC or Chevrolet truck of this type (GMT800 chassis). The base harness has two 3157 jumpers. One for the driver's side (Park/Turn bulb), 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. Resistors prevent hyperflash so you can run LED bulbs. A fuse tap is included so you can also have key-on power to the harness.

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? Give us a call, text, email, IG message, or come by and see us!
