safety chains and 5 pin connector
This photo shows the black cables that serve as safety chains. They're awesome because they always create tension, so they're less likely to come off. Their tendency is to want to coil back up, so the tension this creates keeps em' snug and off the ground. The 5 pin connector has got that blue wire to disengage the surge brakes in reverse - I still have to figure out how to make that work on my truck.
