Received my Acewell unit today...will be wiring it up this weekend....my BMW (using a 1974 R90/6 chassis / wiring) was a mechanical tach unit with points...I'm a little unclear about how to hook up the tack...they refer to "wrapping a wire around the coil 2 -5 times...." I have two coils..they do not address that...Do I wrap both coils? The picture shows them "wrapping a coil (sparkplug) wire" rather than a "coil". Wrap both wires or one?....I don't know....never seen a tach hooked up that way......I'm a bit confused on that one.......
