GTR Lighting Knowledgebase Article: How to install HID Headlights in a Pontiac GTO The 4th Generation Pontiac GTO (2003-2007) can be a little difficult to perform an HID conversion kit install because of the automatic headlights and the daytime running lights. The automatic headlights turn on when you turn the key in the ignition, and the lights do not turn off during starting. Also, the automatic headlights turn on the headlights when the vehicle is off and the remote locks key fob is used. Both of these things do not mix well with aftermarket HID lights. The DRL function (Daytime Running Lights) will turn on the headlights with lower voltage than normal and will cause the HID ballast to not power up properly. Both the automatic headlights and the DRL function should be bypassed or disabled. Lastly, it is easy to do a quad-four headlight modification which will allow both high beam and low beams to be on at the same time. **NOTE: A relay harness is recommended for use during the install on the low beams. Step 1: Install HID Relay Harness on low beams Step 2: Pull the relay from under the hood, closest to the individual fuses, pull the center relay. Flip it over and bend over the tab, or remove it completely, then reinsert the relay. This will allow you to be able to have low beams, high beams and fog lights all on at the same time. Step 3: Remove Daytime Running Light relay: The DRL relay is in the fuse box under the hood. Passenger side right behind the battery. To pull it out you may need some needle nose pliers as space is extremely limited between the relays. Note: You can bend down either pin 85 or 86, all you have to do is disable the relay from being triggered.
