I finally whipped the tether problem on the car lighting problem. I took Bob’s advice ( of course I took Bob’s advice!) and ran the wires along the couplers. It took a loop of wire to make the connections but all works well and all lights are up and burning. I did set two LED’s in the last Observation car posted over the little red back lights on the tailing Obseravation car that makes those red lights appear to be lit up as well. Thanks to all that responded, Jake
