    Does sound better than Scotchlock, then.

    when using the tailight as 'turn on', should I tap into wire at plug right before bulb? Also, do I need to have voltmeter out to make sure which wire is positive? Or, is one color always the 'hot'?

    A voltmeter would be a good idea. You can tap into the wire at any point. I don't have my 1150 anymore but I believe all the grounds are brown so you wouldn't want one of those.

    This is the wire I use for my switched power relays, it won't be live until the idiot light on the dash is off.

    Tap into it somewhere you can reach and easily work on, should you have to. Tapping into a tail light wire near a socket won't make a measurable difference in volts/current going to the relay, so why force yourself to work in the tiny space with very little wire slack and no chances to correct an error?

    Done. I used the tail light and everything works great. I removed factory spade connector at tailight, wired 'turn on' to tail light wire and installed new spade connector. Topped off with shrink tape. I used a posi-tap for tapping into high beam for my overriding dimmer from ADVmonster. Very pleased with the dimmable model 60s.
