For several years I had one dynohub wheel with an SP, but used that one wheel on four different forks. I zip tied the wires to the forks so that I could easily move the wheel from one bike to another without having to re-wire anything, so I needed some extra connectors. I could not find a seller of SP connectors, but the Shimano connectors were easy to find, so I bought them instead.
Since then I have bought another SP and also some Shimano dynohub wheels, I have been using Shimano and SP connectors interchangeably on several bikes with both kinds of connectors, no problem. Other than one being all black and labeled as SP and the Shimano one is partly gray instead of black, I can't tell the difference.
In the photo I have an SP hub with a Shimano connector which is partly gray. (The photo is a bit busy, I have a Tubus Tara rack mounted on the fork.)
