so i've completely stripped my interior, including the dash. i put the steel bar and harness back in and hooked up the guages and now my guages won't work and my headlights do the wave at me unless i hit the button to keep them up. my laptop's busted and has my fsm's on them so i need to know where to look. i'm decent with a multimeter but am not really sure where to start without the fsm's
