i have a brand new LX2610 with a cab, it came with front work lights but not rear work lights, there is wireing already to the brackets where the rear lights would mount , I checked and there is no power to these pigtails for rear lights, either with the front lights turned on or off. can anyone tell me where to get power for these plugs [ where these wires originate?]. there is a blank opening in the dash right beside the front cab light switch, i assume this is for the rear lights, im hoping the wireing is already there [in the dash ] for the rear lights, tia, I tryied search but no luck.
