Let's see here:
Questions; pic 3 ; any thing bolt on here. 2 studs (circled) on steering column bracket.
Just looked at mine and I have them as well, but after looking at my dash frame I don't know what mounts there....hmmm
pic 4 ; where do these wires attach ? ashtray light ?
That is the switch panel light, it attaches to the bottom of the switch frame
pic 5 ; what does a non broken one of these look like. Is my heater switch.
Yeah looks like you need a new switch, did that sucker burn off?
pic 6 ; hearter plug ? where does it go
That looks like the horn relay
