Tacho help

[4dnut]

Hi there newly joined this forum hope that you can help me.

I am fitting a dash from a 85 bronco xlt into a boat running a 302 windsor with a points dizzy and a carb manifold the injection has all been removed. I have everything connected electrical except for the tacho. When I decided to use the dash I assumed the original dizzy would be points as in an earlier bronco but its not. I can not find any electrical diagrams that show the tacho connections. Can anyone help???

If you check this link out I need to know where pins 11 and 12 go. I had hopped that this tacho was an induction loop type but cant tell.

As the original cleveland had a magnetic pickup dizzy I assume there must be some sort of transistorised ignition module but can not find a mention of one that shows tacho hookup.

Am from new zealand so there are not many of these around or people that know much about them.

Thanks

Steve

If you go to this link http://broncozone.com/topic/13341-wiring/ and look at my second post in the thread, I have a few diagrams. one of the diagrams is for the TAC hookup using a Ford Magnetic pickup. That may not work with a point system but at least you can see where the various wires go. I have an MSD 6AL with the Ford magnetic pickup dizzy and it requires an adapter http://www.supermotors.net/registry/media/672663 .

Hope this helps.

Good luck,

Thanks it looks like ones earthed at the dizzy and the other takes a trigger pulse off the coil. Will try it out when I can escape to the shed next...
