1. Take off the stock DRL. We'll start from the passenger side.
You need to locate the stock DRL bulb and remove the bulb from the stock socket.
2. Connect back with the load resistor special decoder. The special decoders will ensure the LED bulbs light up without malfunction issue nor flickering issue.
3. Do the same thing with the stock DRL on the Driver side – locate the stock DRL bulb and remove it
4. Connect back with the special 3-in-1 harness
5. Connect one shorter socket with the 68-SMD 9005 LED bulb and install it back to the daytime running light housing
For the other shorter socket, leave it absence. (do not need to use it)
6. Connect the longer socket with the other 68-SMD 9005 LED bulb and install it back to the passenger housing
7. Turn it on to test the bulbs, and then you are ready to go.
