You are using Weatherpac style connectors with seals on them. The seal is supposed to be crimped if you aren't doing it that way and it takes a crimper like these.

You’re right Blaine. I just went out in the garage and looked. My crimper is almost identical to the one you linked to. That first one I posted was incorrect.
On another note: What are you using for paint on the brackets for the mid arm? Anything specific?
