Tacho wiring

[sowen]

I've had this tacho sitting around for a while now, and have decided to put it in my landy. I've made up a neat spangly pod to put it in the dash pointing at me, not in the way of all the kit and crap in there, then realised... I don't know how to wire it in





There are 3 connectors on the back, a male and female bullet, and a single spade connector. The million dollar question is, what goes where?

that looks like an old current sensing rev counter. I thing you break the feed to the coil between the two bullet connectors and put a ground on the spade. I will have to check my drawings to be sure tho so don't do anything yet. To be honest this isn't a very good rev counter because unless you use the same coil it was meant for it will not be accurate. They were used on points systems as well and I don't know how running on an electronic system would effect it if your using that. Course it needs to be 8 cyl as well.
