I've never seen that particular unit. The ones that I have seen are OEM Bosch or Motorola. They're flatter than the one in this ad. and the wiring ends in with a plastic plug, not in 3 loose wires like in the pic. Apparently, this is kind of generic so as to be able to splice it in to several different style alternators (one size fits all).
