Good point, Troy.  I have used circular connectors on many Velocity installs.  They sure make engine removal simple.  If you go that way give careful consideration to securing the cables to minimize vibration of the cable at the connector, and be sure the cable clamp is done properly.  I like to see the cable supported as closely as possible to the connector, not allowed to hang in free space, and tied down regularly.  Tying directly to engine mount or other tubes without chafe protection: don’t even think of doing that.

A stitch in time save nine (days of overhaul later on).
