Posi-taps are high quality, not to be confused with 3M or other blade-type taps. I solder and shrink when I have wire ends available but use Posi-taps to grab a trigger for relays or to power LEDs (the Skene Design P3s Yarvis is referring to - I have three sets on my bike).
It sounds like Hamlin Cycle did not want the business by quoting three hours. Although, it did take me that long to run power from the fuse block, route the wire to my liking, drink a beer or two, clean the bike a little, etc. My projects always seem to take longer since I love tinkering on the bike!

Those are exactly the lights I was referring to, Skene Designs P3-TS. The lights are just awesome aren't they? Bright as all hell and come with FANTASTIC customer service in Jerry Skene and his business. Jerry told me in several emails that it should never take 3-4 hours. It should be done in an hour or less and he was right! I kept the supplied Positaps for something else down the line.
A job that should take an hour at most shouldn't be stretched to 3-4 and the bike doesn't need to spend two nights there, sorry.
