Help plumbing heater

[Cuzzman]

Hi everyone, I recently bought a 98 2.8 gu and I've just noticed that the heater is not working. I found that there are no pipes hooked up to the firewall. Can anyone tell me where the missing pipes connect up to/what pipes i need?
I can't find any reference on line.

I suspect someone has disconnected it because it leaks so testing it before you hook it up might be a good idea.
