I'm trying to pattern change the Whelen Justice JE series patterns I have three options
1 connector has 2 red and 2 black wires near the middle of the bar..
2 has a black and white wire, when I touch the black it scans the patterns but does not lock
3 connector has a lot of all white blue wires in it .. I'm trying to post pics
