I was reading some posts about temp sensors. I have 69' Firebird 350. When I got the car it had a 2 post unit installed. One wire comes off the alternator and one goes to the dash?

At some point I messed with it and a post broke off. That got me wondering if i should have a single post?

Either way I replaced it with a 2 post since that is what was in it. I put the wires back on as they were. When you start the car the temp light comes on. When it warms up it goes off. I've never overheated so I can't speak to other end. I'm guessing this isn't correct? Coolant level is fine.
