I got a 97 GA/GT and was wondering if this year came with auto headlights. Also if it does where is the sensor located. Thanks

When i owned my 96 GA it had auto headlights, but the sensor was bad and the lights were on all the time. I think it is under the defroster grill.

Thanks because i think thats whats wrong with mine. I was doing a tune up when I got the car and noticed the taillights were on. Anyone got any instrustions on how to get that sucker out. I must have fat hands, hard to reach.

Try search next time, it was the 1st listing under the "How To" catigory:banghead

Ok. 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 dashbehind 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.

independant fogs instructions are available just PM me. Most people have been concerned about DRL and ALC bypasses..
