November 18, 2010 - I'm still working my way through the wiring.
Not quickly, just a circuit or two at a time. The final MG circuit got power yesterday - horns and interior lights. The car has a most hilarious BOOOOP! horn from the factory. It should have two, but one has not yet come to the party.
One of the big debates in automotive aftermarket circles is "solder versus crimp". Solder advocates say that crimps are failure-prone and difficult to do well. Crimp advocates claim that solder joints are likely to crack and fail. Personally, I'm in the latter camp - a good crimp joint works better than a solder joint in the high-vibration environment of a car. It's telling that there are no solder joints in a factory wiring harness, for example.
But the crimps need to be done well. I use good-quality crimp connectors with a heat-shrink sleeve over top. The heat-shrink not only waterproofs the connection but also provides mechanical support for the wire so there's no way for it to vibrate and crack. The crimping tool itself is a ratcheting one with interchangeable jaws. It's a bit harder to find than the usual cheap-and-nasty variety, but you can often find them for $20-40. The ratcheting action prevents the tool from releasing until the correct squeeze has been put on the terminals - most people don't crimp them hard enough.
