Gauges not working
 

Searched and searched and can't find an answer so I had to make a post lol just bought a 92 cherokee 5spd 4.0 and I'm having trouble with the gauges, the speedo, RPMs, and gas gauges don't work, just got a cluster from the JY and plugged it in and same thing those three gauges don't work. Not sure what could be causing this issue.

First thing to check, esp. on the older cherokee's is the electrical grounds. All of them.
