Oil and Clock stop working when the lights come on.

So I have a 91 Wrangler and the oil pressure and clock work great until I turn on the parking or the headlights, my thoughts is a bad ground but I have no clue where to even start looking for it, or why only those three things are tied together. any and all help would be great to have. Thanks in advance.

the ribbon for the gage is missing its ground... need to take the gage cluster apart and clean it.. might look into adding a separate ground as well
