RX7-Diablo269

I have an 87 Mazda RX-7, I have an aftermarket tach that i've been trying to install for a while now but I can't seem to find the tach lead anywhere. I have tried many places but can't find it at all. If you know what I can do to get this hooked up please help... Also it's a Sunpro tach (sunpro is owned by autometer).

It's off the trailing coil and is either a solid black wire or a green one. I can't remember right now.

On a different thread, Mike said there is a bullet connector wire off the trailing coil for testing.... I think it was white with green??
