This is only for OEM headlights not aftermarket headlights.
now has the harness available to replicate the look of the LTZ models DRL's on your 2015-2019 non LTZ Suburban. This plug & play harness will disable your headlights during the day and utilize the LED strip, in the headlight, as DRL's. The LED intensity will be the same as nighttime intensity, unlike the LTZ which is brighter during the day, this is due to the fact that the LTZ headlight is different. Nighttime function will remain the same, you just gain the added look of the LED's during the day. There is no programming needed and install is very simple. Please note the LED intensity is the same day and night.....
With this harness you will lose the ability of just having the parking lights on. Anytime the parking lights are on, your headlights will be on as well.
AFTER THE INITIAL INSTRCUTIONS WERE MADE WE DID ADD A CLEAN POWER SOURCE TO THE HARNESS. PLEASE CONNECT THE RING TERMINAL WIRE TO BATTERY POSITIVE.
