left ND switch block question - eliminating the parking light circuit

Over the years I've always used proper crimpers, with or without solder afterwards, and always use heatshrink.  Have never had either method fail.  Nowadays I prefer to skip the solder.  If your wires are properly crimped and supported (i.e. no strains from tension) then failures are very unlikely.

+1! in the Telecommunications world it's a big Boozo no-no to solder stranded wire in a crimped connector.
You're just asking for problems out on the road.....

Agree, however in Military Electronics world (harsh environments) it's been done successfully. The key is not to allow solder to flow past the crimp. Once solder flows past the crimp and under the wire insulation the flexibility of the wire is compromised and vibration/temperature cycling will cause the wire to fracture over time.

For the average (inexperienced) Joe with a $10.00 soldering gun chances for success will be low.

HI, due to area where most of my riding is done ,which is north wales snowdonia in particular. we crimp and solder because it gets as wet as having a bath. needless to say once you've been stuck at the side of the road for hours you get to thinking I should have soldered . this is of coarse just my view as somebody who likes peace of mind and riding.

When I did my navy soldering course, we were taught to tin the wire, crimp the connector to the wire then solder the wire and connector. It was a big no-no to allow the solder to whick down under the insulation, but we had specialised equipment such as heat sinks to prevent that. Heat shrink was a relatively new invention then, we mainly used pink Hellerman tubing. Then we learnt all about wirewrapping.
 
Agree Terry. I've wired a couple of boats. If you don't solder the terminals they will soon fail because of corrosion between the copper wire and the crimped terminal. The copper goes black in a marine environment, often for a metre or so up inside the insulation. By marine environment I don't mean underwater, or even wet. It must be the salty damp air that corrodes everything to bits.
