daytime running lights won't shut off

My 1993 Isuzu Rodeo daytime running lights will not shut off any ideas? I have been told to replace the daytime running light module...........does anyone have wiring schematics that show where this module is or which relay is connected to the lights? I have wiring diagrams that say that this truck doesn't have DRL..........I beg to differ as mine won't go out..............help

This is going to be a hard finding an answer since the Isuzu day timing running only were offered in Canada
