Tom and his son bought the spare USE S10 battery box from me some time ago and installed it in their ’84 S10. At Saturday’s SJEAA meeting, I asked for input on how to get a BMS data cable into the #1 trucks’ battery box while keeping it water tight. Tom knew the answer because he knew the battery box better than I did. By removing the drive shaft, the wall of the box that holds the watertight connectors, is exposed clearly from under the truck. That way I can see if how hard it would be to drill a hole and add another watertight connector. The hole would need to be something like 5/8″ to 3/4″ in diameter. Someone talked me into using the water tight connectors that don’t need a threaded hole to be mounted. That translates into less work in a tight space under the truck. Thanks Tom!
