Depends on how good its got to be, some are simple, not every connection demands tha same attn., heat tubing etc and in fact rarely use it. For connections where its a real issue usually enclose the stuff in a box and use wire nuts with them sitting up, after they are installed I spray the pee in them with a straw and whiz a little around inside the box. The stuff capillaries down the wire and keeps water away, even under constant road grime and pressure washing they often look new if they are removed a decade later.
Heat shrink is about like powder coat, water often seems to get under it and once it does its a hidden problem. Another simple way is a wire nut full of silicone, I pre twist and its a done deal.
Some of these were put together piecemeal, but they work well and will come apart if the screws were sprayed when installed. I smear a little goo around the top and sides of box, leave a drain in the bottom.
Boxes can cover mounting studs and it they use bolts often turn them around and put nuts inside the fixtures.

Sberry the OP is currently using a good connection method executed poorly, and wants to take a step forward. Your suggestions would have him spend money and effort to use a poor method executed well, a lateral move at best. Wire nuts don't belong on a moving vehicle, and I'm certain there's not room for junction boxes on his motorcycles.

You definitely do NOT want to solder a crimped joint. The solder makes the wire brittle and it will snap on with enough vibration.

Ok, got it. I didn't know that such low temperature would affect the wire. Thanks for the advice!

The heat of the soldering can make the insulation brittle, but that's not what he was talking about.

Solder can wick up between the wire strands, making the wire stiff at that point. From there, the stiffened wire will put extra strain on the outer strands as it bends, which will cause them to eventually break. That creates a crack that will work its way down through the wire.

Stranded wire is stranded for a reason. It needs to be able to bend freely. Restricting the motion of the strands in place with each other as solder does, leads to premature failures if subjected to sufficient vibration.

I agree, I was just shooting **** about various methods. I just demo some had been on a truck 20 years, looked perfect inside and never failed.
I seen lots of stuff fussed over that had a short life span.

I like to use uninsulated crimp connectors with adhesive lined shrink tub. I have never really found a good assortment kit of the uninsulated variety but generally go through more **** connectors anything so just buy them from NAPA.

Here is a thread from a while back on crimp vs soldier as that is bound to come up again:

That's what I do as well.
