Connectors or Direct solder for esc & motor?

[brijar]

I know this is a rather old post, but I just bought some 3.5mm connectors for my motor and controller because I was always switching my BL system between my Maxx and Rustler and having to remove the controller with the motor at the same time was rather annoying.

Anyway, I was wondering exactly how you solder the gold connectors to the wire. My motor and ESC wires are pre-tinned, so I can't fit them into the non plugging part of the connector. Do you just solder the wire to the top of the connector? Also, can I put some shrink tubing on the female connectors so that they won't touch and short something out?

Thanx,
Brijar!!!
