    I bought this coil kit off eBay,,, anyone know what coil is the primary and what one is the light coil? The condenser that came in the kit fits the Mitsubishi stator plate and the mounting holes are in line with the Mitsubishi plate so it’s definitely a Mitsubishi kit that also came with points…One coil has two leads and one ground that grounds under the mounting screw…the other coil just has two leads with no ground. The stock Mitsubishi stators I have there’s a wire running from the primary coil to the light coil. Any Mitsubishi gurus out there that image.jpg image.jpg image.jpg image.jpg know how to wire? The package says fits a Z50 but I’ve never seen a z50 with a Mitsubishi ignition? Maybe in Japan?

    @allenp42 is the guru.
    The one with the 2 colored leads is the light coil.
    They didn't give you the jumper between coils, and you should be ok without it.
    Just wire it up the same as your old stator. There are a couple good threads that have pics if you need guidance...I could look them up for you.

    Ok..so the primary coil has two wires ,,,I know one goes to the condenser but where would the other wire go? On The factory coils it’s sodered to a spot on the light coil but these new coils have no spot to Soder it to?

    You would just ground it under a mounting screw on the leading end of the coil...same way a regular Hitachi primary coil is mounted.
    I'll find you a thread to reference.

    In that thread above...you can see how Mitsubishi gave the primary coil a little boost from the lighting coil. There are only 8or10 windings on the lighting coil that run over to the primary coil.
    You won't have that on your new coils...so just mount it the same as...every other Hitachi primary coil.

    If the coil fits the plate, you should be fine. As kirby mentioned, no need to worry about the wire from the primary coil not connecting to the lighting coil on aftermarket coils. I have only seen/touched a couple of different AFT Mitsu lighting coils and all of them had one end grounding like a Hitachi. If you hit a snag, drop me a PM. I have a few aftermarket lighting coils for a Mitsubishi setup. Also, the coils I have are a lot stronger (lighting circuit) so your HL will be a lot brighter. Pretty sure I have a couple of used Mitsu coils if you want to keep original.
