Hope that helps you out :)

Try a electronic flasher. Wire power to flasher from light switch. Then wire flasher to lights.

did you leave the key on and kill the battery or a light or something double ck that battery , they will still light up the ignition and lights and ll but does not have enough to crank the starter , that is what is sounds like to me be put a jump on it or charge it and try again , when you turn on the ignition does the lights light up on the dash panal if so the batter is low

black-ground
yellow-white accesory
red-green- 12v constant.
generic application colors.

use a voltmeter and a 12v light to verify all connections.
