Installing a set of ISS Pro's in a 2002 Excursion. Looking for the power sources for the lights and any recomendations for the key on power source. I know I have seen it here 30 times, but cant seem to find it today.

thanks for any help/links etc.

Edit, Red with yellow stripe off head light switch is headlight on power, put a fuse with wire into empty key on position hot port.

 

Just left of tranny hump under the dash, you'll see a blue/pnk trace wire just hanging around. That's a 12v switch power, also

 

Don't run the lights off the dimmer circuit for the dash lights. You'll overload it. Just have the lights on all the time, you won't even see them during the day.
