so you are saying touching the wires together / un-together definitely cycles the compressor on/off !?!?!?

Yes. Working 100%

Make sure you are wiring the 5V and signal wires correctly. If you send 5V down the signal input on the side car it will overheat the side car board. This can cause the resin on the board to become a liquid and start to flow. It can even become hot enough to desolder the connections. Depending on the duration and extent of damage the side car can sometimes be repaired. Most of the time it is permanent.

If touching the (2) wire ends that you removed from the pressure switch toggle the compressor on and off it can only be a defective pressure switch. Essentially, that's all the pressure switch is doing, connecting and breaking the circuit at the low and high pressure setting.
