Question Jacobs Marine Master Ignition diagram needed

I need wiring diagrams &/or installation instructions for a Jacobs Marine Master ignition.

Jacobs sold out to Mr. Gasket and I have spent 3 hrs on hold for them with less than satisfactory results.....
even Summit could not get an answer from Mr. Gasket techs.....

Please help!!

Not sure about their marine products but I bought a system for my 94 Bronco and it was a piece A big waste of money....Went thru 3 coils..Tech support was great and they replaced with no questions or cost but still a waste of money. I didn't notice any gains in milage or power....Really thru off my buddy's snap on scanner....Bought the D.U.I. sytem for my boat and was thrilled with it.....Just my two cents

Actually added a Jacobs to my first "Blown Formula".... it ended the fouling of spark plugs and added 500 rpm on the top end. I thought it worked great.

Now 3 years later... I need the documents on it.

Help!!

I have had on since 1996. Same results as blown formula. Works great, plugs read very well, but the biggest improvement came in the mid-range.
