It depends on what year your car is. The later years respond differently. I believe its 01-03 that has an annoying clicking if the fuse is pulled to disable the auto light feature. For 98-00 you can just pull the fuse for the auto headlights as well as disconnecting the DRL diode to disable the DRLs. Not sure about 97's. I pulled the fuse on my 99 to disable the auto headlight feature and have had no issues.
