On my alpha spid i installed a 4 wire trailer connector and i tape the wire 
very thigt over entry tube where the wire are passing through. Dont forget 
to put silicon over the terminal box top but let the bottom free to allow 
moisture drainage.

Dont use too heavy wire gauge with the trailer connector wire size you will 
not get any problems. As many terminal connector they are not made to 
hold any charge and i prefer this system to my former tailtwister with the 
bottom terminal connector where you have to dismantel the rotor to acces 
the terminal. Alfa spid is making a very accessible terminal box but not 
strong to a point to be used as a guyed wire attachment point.:)

Your idea to tape the rotor cable is the solution that i used too to avoid 
any stress on the terminal post.
