We have also incorporated a bracket and automotive quality 10 pin socket on the side of the plastic frame (not shown in this pic) and ALL wiring goes through this plug.

4 screws and one plug and the entire mech is in your hand!

Back to being serious for me...

Why 10 pins?  Two for the coil, two for the switch, two for the bumper light.  A common ground would reduce the count, but how would you get more than 6?  Daisy chaining perhaps?

Regardless of the number of connectors, its nice to see the use of easy removable plugs.  I presume the 'automotive quality' is to ensure the regular shock and vibration doesn't pop the connector open?
