8 pin connector

2 questions

I have a Pathfinder 2kW Product code M92650
serial #1020267

I need the 8 pin connector going to the radome - where can I get this?

I cut the cable half way down and need a box or something to hold the new splices. I know folks don't recommend this, but any recommended junction boxes/fittings, etc. Thanks.
