T800 Overhead Warning Cluster INOP

Good day all,

I recently purchased a 98 T800 at auction and am starting to realize it may have a bunch of electrical issues. Mainly with key switch on, none of the warning lights will come on. It also does not have an operable warning low air light or buzzer. I am not sure if this is all symptoms of the same problem or a buch of individual problems, any guidance would be definitly grealt appreciated. Also the previous owners looks to have run a wire straight to the fuel cut off solenoid on the pump. The original wire it just hanging, I hooked it up only to find the truck will run and die intemittenly, there is no consistancy when this will happen. sorry for the long thread I could really use any help possible.
