I got the cigarette lighter fixed and no more false alarms on the radar detector.
I thought I had the Tach fixed by doing a little solder work. However after a couple days of driving it went back to its normal bullshit. I think I'm going to pull it all out again and see about replacing the capacitors in the tach.
Also, I have been getting after the air bags. When I pulled the cluster I noticed someone took the air bag bulb out. Then I noticed that the air bag control module was unplugged. Once I put everything back I am getting a 7 flash code which is implying something wrong with the passenger airbag.
Another issue I am tracking down is the horn not working which I am starting to believe is somehow related to the airbags.
