Build your own shift light or RPM indicator?
Does anyone know of a book, magazine, or site that talks about this? From what I hear shift lights only tap into one wire (?) and I can't imagine one wire from the ECU contains 150 bucks worth of technology/circuitry from Autometer or another brand.

Well take an oscilloscope to the signal wire and graph out what you see. It shouldn't be hard if your an electronic's buff to make something simple to turn on at x voltage...
Goodluck. Personally all the time a manufactur puts into designing a unit that works with virtually any car, comes in a presentable package and offers some type of warranty, is rather cheap at $150.

Yeah, but then you have a big giant black thing on your dash with a big ugly yellow light! I just want a small LED light to flick on at XYZ RPM... I will figure it out over time I guess.

You need to stop browsing the local APC authorized dealers.
