Need help on a few interior items

Hello everyone. I'm working an a 70 Dodge Challenger. I took it apart but it's been a while since I've worked on it.

I have 3 pics. The front seat belt with a plastic cover. I don't have the detail as to where it goes or rather how it fits.

The hazard or signal . I thought it went in the dash and one went on the side of the ashtray ?

What is the last pic. it has 3 yellow wires. It's metal, round and warm when the car is on.

Also I have different lengths of seat belt bolts. Will they be obvious when I go to install them? Any help appreciated.

Several lights I'm sure go to the ashtray, Automatic and glovebox maybe?

One flasher attaches to the side of the pedal assembly and the other to the side of the ash tray assembly.

The little light goes above the cigarette lighter. The long orange wire does to the center console shifter light.

The seatbelt cover just sits cover the seatbelt assembly. It gets sandwiched between the seatbelt assembly and the colored plastic piece that the seatbelt goes through.

The different lengths are for the number of belts that it holds. Locations by the door sill have only one belt (short) and the ones by the tunnel have more than on belt (long)

Thanks Morty. That is a big help. Any idea on the silver round metal piece. I've seen it before and don't remmeber what it is.
