Get rid of them cheap connectors and buy some connectors with "Pig tails" on them so you can just solder the wires together and not worry about soldering the connector part.
I definitely do not recommend doing that on systems like this with the multipin round "higo"/etc motor connectors.
I recommend leaving the existing connector, as now that it is fully plugged in, it is water-resistant and typically quite sufficient for these power levels.

Glad you got it running. I would consider soldiering at some point, but for now go with your tape idea.
Since it's fully plugged in now, it's unlikely to exhiibit any further connection problems at that point.
Soldering is unnecessary, and would require cutting off the connectors, and matching up all the wires, cutting all the wires in such a way that none of teh splices are going to overlap each other (so if something goes wrong with teh splice insulation they still can't short to each other).
The solder connections, even with heatshrink, will not be as water resistant as the existing connector, so under rainy/wet conditions it's likely that water will eventually wick up into the conductors inside the insulation, and corrode the copper. (this even happens to my wiring here in dry Phoenix, AZ, after the short rainy season, even when things don't get all that wet).
Tape is also unnecessary, as these connectors are quite difficult to undo once correctly and fully plugged in.
