Guest EOppegaard Posted June 19, 2003 Share Posted June 19, 2003 I am looking to install a wig-wag flasher on my high beam headlamps, however I am having trouble determing which wires do what leading into the headlamp. I have a 1993 Subaru Legacy Wagon, stock headlamps. Anyone know what wires go to what? Or if the headlights use ground switching instead of 12v positive switching? Any Help Appreciated!

Guest scoobtech Posted June 19, 2003 Share Posted June 19, 2003 Just use a test light at the headlamp connector to find which wire does what . One wire will be ground all the time & the other 2 wires will be 12 volt . Only 1 12v wire will be live on headlamp high & low . :x Quote Link to comment Share on other sites More sharing options...
