1999-2014 GMC & Chevy Truck DRL Grille Accessory Lighting Harness with Optional Doubleshot

While designed primarily to power our brand of lighting accessories, this harness can be used to power just about any forward accessory lighting that you have:

The harness will work with any full size 99-14 GMC or Chevrolet truck with the GMT800-900 chassis. The base harness has three 3157 jumpers; one for the driver's side Park/Turn bulb, one for the driver's side DRL socket, and one for the passenger side Park/Turn bulb.  Jumpers allow you to continue to run your stock DRL and park/turn signal bulbs. Resistors integrated into the harness prevent hyperflash so you can run LED turn signal bulbs.  The output of this harness is two female 9006 connectors with power, ground and turn signal.  This output can be used to power just about any DRL/Switchback Turn Signal LED lighting in the front of the vehicle.  The 9006 connectors can be removed and the wires spliced to connect any lights you may have which do not use the same connector.

It is very important to use the included dielectric grease in all sockets and on the plugs.  If you do not, the contacts will corrode and cause issues.  This corrosion is not covered under warranty. 

OPTIONAL DOUBLESHOT: Want even MORE light, we have you covered. Our exclusive DoubleShot harness can be integrated into this harness. This upgrades the stock configuration of One DRL and turn signal bulb per side to Two turn signal and DRL bulbs per side.  It is a nice look and will require a total of four Switchback bulbs (two per side) to utilize properly.  The DoubleShot upgrade is shown in the item images.
