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!

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
