97-02 drls in older fbody

The DRL module functions this way: When you switch on the ignition, it switches the turn signal filaments to a constant 12v circuit (always on). Then when you operate a turn signal, that signal from the switch is read by the DRL module, which switches that turn filament back to the turn switch/flasher circuit. When the turn signal completes, it goes back to constant 12v. It takes about 1-2 seconds to do each switch.
Also, there is a light sensor in the dash on non-US cars that switches this on during the daytime. On US cars, the sensor is deleted, so it stays on all the time.

Finally got around to figuring this out. Stumbled across this. http://www.webelectricproducts.com. They make a drls for 96-96 vettes. I ordered the module and installed it in my firebird. And it works great. Drls have factory functioning.
