Perhaps
@Mittzy could offer brackets
SO do BOTH harnesses (stator and Output) require extension, or just one or other?
The stator is a stand-alone harness, wo you may have more flexibility with that one? (I really don't know, just thinking out loud)
Alternative for output is not to extend from the OEM connector, but just make up new output harness which would go straight to battery (the positive would have Fuse in-line)
However the output harness extender is relatively easy to do, converting the OEM to a 2-way female (since only two terminals are used) mating to a 2-way male on extender and the other end of extender being a std 3-way.
It's the 3-way for stator connector that is more of a pain ....
