This is only for OEM headlights not aftermarket headlights.
This harness is for those with 2015 (New Body) and 2016-2022 Chevy Colorado's that are looking to remove the DRL function from the headlight low beam bulb.
This version of the harness is for those running stock or LED headlight bulbs. If running HID bulbs please refer to our HID HARNESS
This harness will disable your current DRL function from the headlight bulb and allow the parking light to be your DRL instead. The headlights will automatically come back on at night when headlight switch is left in Auto mode.
For those looking to add LED turn signal/park bulbs please select the appropriate option. This option will include load resistors already added into the harness. Bulbs are not included.
If you are planning on running switchback bulbs in your truck, please know that there are many different manufacturers out there, and many of them do not function in the Colorado's, they will actually produce a strobing effect as the internal capacitor in the bulb does not properly match the output from the truck. If you install switchback bulbs and experience that issue, please know it is the bulbs and is not the harness causing the issue.
After install, please confirm the following for DRL mode.
Switch in Auto
Engine running
Adequate light hitting the dash sensor
Truck shifted out of park. If in park no lights will be on.
When the above conditions are all met, you will have just the front ambers on
