Hooking up a SW Geenline tach with internal sender?

I picked up a SW Greenline tach at a swap a couple of months ago and I am about to install it in my '56 Stude. This is the later model that doesn't require an external sending unit. I can't find any install instructions on line and I was hoping someone here could point me in the right direction as to how to hook it up without frying it!

I know this makes me look like an idiot, but . . .

 

What colors ya got for wires?General= blk-grd grn-coil yel-light red-hot

 

No wires with the tach, but here are a couple of pics.

 

I found this on line, but none of the stuff here applies:

Nobody has answered this? I have the same or similar tach and I'd like to know how to wire it as well...

 

I think that one still needs a sender. They had external and also internal (mounted on the back of what you have but inside the cup). Yours is missing. If i can remember i will shoot a pic of what goes on the back of yours.
