Tach wiring help?

I've been looking for inexpensive tach for my truck that would look old. I've found a few Mercruiser tachs that were used on Chevy 6 cylinder engines. Rev range is perfect for a stock 230.

Can anyone tell me how to wire this? Does it just need 12V and coil, or one of the senders?
