Electrical Factory water temp gauge setup?

I have a 1985 CJ7 with a 258. Much of the engine wiring has been modified from stock and I'm trying to remove the hacked-on aftermarket stuff and get the factory gauges working again. I'm trying to figure out exactly how I should be setting up the factory water temp gauge.
What does the factory setup for the water temp sender look like? Specifically:
- What port in the intake manifold (or other location) does the sender use?
- What type of sender is factory? How many wires? Part number?
- How is it wired? Does it take 12v switched and send the signal to the gauge?
- Which wire is which? I have a hacked-apart painless wiring harness and no good way to figure out what wire goes where other than manual tracing. I have identified what I think is the wire that goes to the factory water temp gauge but I'm not sure what the rest of it should look like under the hood. I'd hate to buy a sensor and pigtail and then learn that it's an aftermarket part that doesn't work well (or at all) with the factory gauges.
Thanks! The more detail the better. Bonus points for pictures.
