Dazzler an sx3 is a bit hard if you want a tidy job with all the belts in the way,yeah use banana connectors but def insulate em properly, if your uncertain about damaging the esc dont risk it, pay a few quid on the connectors at least this way you can run the esc and make the right adjustments later when you or someone else can do the job the way you want it.
Get some short 3.5 mm male and female and a bit of heat shrink
