Here's my 2 cents...... Good quality crimp connections are acceptable so are good quality soldered connection. The big reason they fail is when they are not protected from the elements. Quality double wall heat shrink tubing is your friend. Use the right size crimp connector for wire size, soldered connections require the right amount of heat and solder ( insert practise required here ) too little heat or solder= poor connection too much heat or solder= stiff and brittle joint. More fuel on the fire

How about THIS for a technique: One of my buds out at the airport who is currently building his 4th or 5th aircraft, crimps all his joints/terminals without the plastic crimp,... just a plain metal terminal. Then he puts on a light coat of RTV, then heat shrink tubing. When he heats and shrinks the tubing, the RTV skooshes out each end.

He explains his method is the securest and most reliable of all because it is easier to crimp plain metal more securely than metal covered in plastic, the RTV glues it all together and provides complete weather/oil/heat resistance, and the heat shrink tubing, which is now glued to the terminal, provides fatigue suppression because of the strain relief where the wire enters the terminal.

All that may be true, but it is slower and kinda messy.

Gyrobob is right that crimp connectors are preferred in aircaft over soldered connections, because under high vibration the wires are prone to breakage right where they enter the more rigid solder. Crimped connections tend to withstand more vibration by distributing any deflection over more length of each strand, they're not as strained and fewer of them break.

Whether this translates to "better for motorcycle connectors" is debatable, because with motorcycles the concern is less with vibration and more with the joint's exposure to the elements. I would guess that joints fully sealed in shrink tube are probably best crimped. This assumes the weatherproofing is perfectly reliable so that exposure to moisture is the same as in an aircraft hull.

And I would also guess that joints that are so fretted over, are going to outlast the rest of the bike, and thus we should go with our favorite, make the connection, and get a life. Grin

I think I'll get my retired mechanic buddy to do it LOL. The plan is 2 lights hooked up to the brake light. I assume I just solder the wire to where the brake wire is connected to inside the light if I can. If I have to splice into the wire myself, I think I'll go with crimp, heat shrink and liquid tape.
Routy, now you can replace your rear tire.

great alternatives to both solder and crimping are posi-lock connectors. you can't get an easier tapping method than than a posi-tap. their only drawback is that they're bulkier than a nice shrink-wrapped crimp or solder joint.

i've had some in use for 5 years and am really happy with them, and the folks at webbikeworld think highly of them too.

Now gentlemen,

Each of you take your favorite tool in your right hand. Take the left hand of the person you are disagreeing with and apply your tool to his little finger on his left hand at about the first joint.

The first one to flinch or squeal loses the argument.

=============

Me, I like interlaced or twisted wires, solder it, fold it over and apply two layers of heat shrink tubing well shrunk with a hair dryer. Winds up just being a little bump in the wire.

Then I take rubberized cloth tape (old school wiring harness covering tape) and extend the wiring harness proper to hide my joints forever.

I also like to lightly crimp on a terminal with a crimper, then I hit the fray end past the crimp with the soldering gun to block off all moisture/air by wicking solder back through the crimp and up the wire a bit.

Grin

Overkill, that's my philosophy ....
