Key won't kill it and the needles won't move. Help?

[whitesswj]

I need some help.

The key will not kill the truck.
- I've changed the switch thinking that was the problem but it wasn't.
- I rewired one wire that I think went to the starter, I dunna know.

The temp guage stays at about 75% twoard Hot
- It did work at one time when I put the engine in it and it had a new sending unit in.

The ammeter I'm not sure ever worked even with the old voltage reg. I know the wiring is correct there.

Ideas?

it's the '68 in my sig.
