it will change patterns on the corner strobes but nothing else changes i use same wire and only activate rear modules it just alternates every other light and will not do any other pattern front also has 2 lights and will only wig wag not go to any pattern i bought the bar second hand and has alot of black wires black /green black/blue etc but they are all connected in the middle of the harness and the guy said they was grounds im not sure if this is right or if there is something wrong with the boards maybe? any thoughts? i had a liberty and it had a power cable and control cable but this bar is different it has a traffic adviser that dosent seem to do but one flash pattern no matter what i put the dip switches to or left right center flash all do same thing but the bar has a cable going to the advisor and a large cable that if i hook 12v to some wires seems to control td ally corner front and REAR AS A WHOLE is this correct or is the wiring screwed up some how
