i dont think the rear ios sagging to much cause the front fenders are cut pretty high.

 

I just bought that same tach, was it tough to hook up? What did you connect the wire to, to read the RPM's?

 

It's not my cherokee i'm looking into buying it most tachs the green wire goes to your coil ground the black one good white is your light and the other is your power run it to your ingnition switch also some tachs have wires to cut for 4cyl 6cly v8 you leave them alone
