1) correct they get speed nuts like the vent have on your pad ..
2) I should have a picture of my 69 dash grounds.. the one you will be missing is the one to the tach as you had a blank there b4 ... the rest all fit in one spot only because of their shape and dimentions
3) those are plug ins for the clock ,,,, anything orange is fulltime power 12v
so its power to the clock .... lighter may be a spade but usually its a round
plug in ,,,, rochester for sure is .. cascos are often threaded .. rochester a nipple
3)b the gray plug in gray is always a power wire from the,or for , a light
so thats the clock light power source there may be a trimmed gray hanging lower
one is for the heater control the other is for the radio illumination light
4) there is an optional harness for the dash tach and the same one is used for the clock
for illumination .... I may have a spare ...
I will look after the Mariners get spanked by Oakland
update with pictures ,,,, I have an original light harness but it needs a solder ,, repair
