I have traced down the ends of the gray and black harnesses to my lightbar under my console, but the Scan-Lock wire isn't there. ???????? To my understanding, one of the harnesses is a power harness and should only be two wires. The other should be a 17-wire harness, but these two have about 4 or 5 wires in them. Is it possible the wire doesn't even come down that far and is up next to the bar itself? The pattern this thing is on MUST be changed at once. It's horrible lol

Here is the wiring code from one of my Libertys (Mine has the 17 wre function wire cable):


Wire Color Function Fuse


GREEN . . . . . .Front Corner LEDs . . . . . . 1 AMP


BLUE . . . . . . .Rear Corner LEDs . . . . . . 1 AMP


GRN/WHT. . . .Front Outboard LEDs . . . . 1 AMP


BLU/WHT . . . .Rear Outboard LEDs . . . . 1 AMP


GRN/BLK . . . .Front Inboard LEDs . . . . . 1 AMP


BLU/BLK . . . .Rear Inboard LEDs . . . . . 1 AMP


WHT/GRN. . . Right TA . . . . . . . . . . . . . . 1 AMP


WHT/BLU . . . Flashing Alley & T.D.’s . . . 1 AMP


YELLOW . . . Pass.-Side Alley Lights . . . 1 AMP


WHITE . . . . . Driver-Side Alley Lights. . . 1 AMP


WHT/BLK . . . Take-Down Lights . . . . . . . 1 AMP


WHT/ORG . . Cruise Lights & AUX . . . . . 1 AMP


WHT/YEL . . . . . Left TA . . . . . . . . . . . . . 1 AMP


WHT/BRN . . . . .Rear Center LEDs . . . 1 AMP


VIOLET . . . . . . .Hi/Low Power. . . . 0.5 AMPS


WHT-VIO . . . . . .Scan-Lock™. . . . . .0.5 AMPS


WHT/RED. . . . . .Front Center LEDs . . . 1 AMP


NONE. . . . . . . . .RFI shield drain / to ground


Activating WHT/GRN + WHT/YEL = Split TA


It would appear that you are seking a WHT-VIO wire among those in your harness(s). Do you have one of these in the wires that are connected to your Liberty?

All of my wires out of those are solid colors. There are no striped wires. I'm not sure if this is the wrong ones or what. But under the lightbar, going into the roof, are a black harness and a gray harness. These (I'm assuming) come out under the console. I don't really need the scan-lock wire at the console, I just want to know where it is so I can change these patterns.

My liberty bar had the main power harness. The control harness and the small gray sheathed wire for ballast control. So 3 wires out of the bar. The old style ballast led.

STP, I think that's exactly what I'm looking for. Those are the same colored wires in the harness under my console. Dumb question here, but what is considered "Ballast A" and "Ballast B" and so on?

Each ballast controls a certain pair or pairs of lights. You can change the pattern for each ballast or set separately.

Ok I'm getting quite irritated with this bar. I went back under the console and here's what I found w/ the harness. The gray harness has a red, white, and green wire, all 3 running to the switch panel. It has a black and orange wire going to the ground. It also has a blue wire that is just clipped off and isn't used.


The black harness has a white wire and a green wire running to the switch panel, with a black wire and a bare wire going to the ground.


I tried applying 12V to the blue wire w/ nothing happening. If it helps, this is the Liberty Economy version bar. There is no striped wiring anywhere in either harness.

You have an Economy Liberty. It doesn't sound like you have the optional scan lock cable installed. You will have to open the bar to change patterns. There are two ULF22 flashers inside, one for the front, one for the rear. The scanlock wire is missing out of the connector on the flasher. You'll have to use a piece of wire to activate the scanlock function on each flasher.

Thanks a lot Philter. It's supposed to be decent weather here tomorrow so I'll attempt that. Hope it works. It's on that ugly-ass SignalAlert pattern that does 3 cycles of alternating and 3 cycles of simultaneous. I'll let ya' know how it turns out.
