Dummy Light to Gauge dash swap chaos! Help?

[67stepchic]

Thanks for all the info guys! Honestly to do this all right I'd probably be best off re-wiring it from the ground up, but at least for the time being I need this to be a running/driving vehicle again The electrical stuff can either be really simple or really complicated and I just need the most straightforward approach that lets me work with what I've got for now.

Let's just say after two dash fires and a slew of other issues, where I'm at now is light years ahead of where I was when I started! You guys have offered up some great info and I do appreciate the input.
