F**king DRL's

I won't buy a vehicle that does not have DRL's. I think DRL's are a safety feature that should be required in every vehicle made. I went to look at new cars and asked the Salesman to start the vehicle and if the DRL's did not go on, I tell the Salesman the vehicle is unsafe and would not purchase it. I think for the coat of bulbs for the DRL's this is a very economical safety feature.

1999-2000 Pontiac Grand Am This I know for sure works on 99-00 model GAs. This makes for an alternative for the DRL kits that are no longer in production. There is hint that a fully Plug and Play version is underway which I would recommend if you want to return to stock easily. If you are brave enough to mess with the BCM wiring there here you go.
First do not remove any relays or fuses; however, I highly recommend that you unplug your negative battery terminal.. Don't want to risk popping fuses or pooching the Body Control Module (BCM).
The BCM is located on the passenger side under the dash. There isn't much space to work with so to get the most space I would recommend that you remove your glovebox as well as the under dash panels. The BCM looks like a black box about the size of a CD jewel case. It will have 3 connectors.. 1 pink and two gray.
No DRL
At the BCM, locate Connector C2 (center) On the "B" side row of pins, locate the dark blue wire (b4) Cut this wire, leaving as much as possible still attached to the BCM.
Now simply add on a piece of wire to the side that is still connected to the body control module. attach this wire to a good ground, like a screw in the metal part of the dash behind the glove box or I used the interior light mounting bracket screw right there next to the BCM.
The BCM now see's this to mean that the regular headlights are on, and so it energizes the relay that turns off the DRL's.
ALC bypass
At connector C2 find A3 the yellow/black wire, and B2 light green/black wire.. be careful because there are two light green/black wires on that connector.. the one you want is closest to the yellow/black wire.
Cut these wires again leaving as much wire as possible attached to the BCM.. simply tie the two wires together and tape them up real good. (this is the same thing as removing ambient light sensor and adding a jumper wire)
The BCM will now think that it is daylight all the time and it will not energize the relay to turn on the headlights.

for a grand prix but works on my 03 Monte. Did the drl disable before installing my led high beams.
