Can y’all help me out. I have no idea what I’m doing

Loose wires in 1993 5.0 V8 F150 Engine

All warning lights came on, the odometer did not.

It sounds to me like the fault is within the instrument binnacle or associated wiring as opposed to the lights being genuine warning lights. It sounds like a classic "shorting out" problem. This ...
