Steering shaft question

Yes, you are correct, with the emphasis on PROPER crimp joints. I've had mixed success using crimp connectors, even after investing in a decent crimping tool.
In my experience, a properly cleaned and fluxed solder joint between two wires is far more reliable, particularly in a flexing situation, than a dodgy crimp where wires can be pulled out or corrosion can easily start. If someone is not capable of soldering correctly, by all means try the crimp method but to be honest, two wires twisted together and back on themselves and well taped up may be their best option.
