How do you wire the corner lights to blink?

Someone said to use the positive wire from the blinker and wire it to the positive on the corner lights that way they will still be used as parking lights and they will blink. My question is Which wire is positive??? The driver side is green and black and the passenger side is black and black... So which one is which? If someone could help me out id greatly appreciate it.

Thanks,

Johnas

look for the black wire that is only black. this should be the ground. The other two, green and probably black w/white, or red, or... some other colorshould be positive.

Ok thanks.. But is it true that i can use only the positive wire to make it blink and be a parking light? Also do i need to change out any fuses???
