I can look at a wiring diagram and find lots of wires and connectors that provide 12V ignition switched power, but I'm not at all clear on the best way to physically get at this power. Should I strip insulation and solder? Use some type of fuse tap or wire tap? How do people jam wires into relays (relay tap?)? I'd like to do this correctly given factors such as weather, vibration, and the tight space available on a motorcycle. Photos would be much appreciated!
