I have an 05 KJ Liberty that I need to get the tachometer off and use in the dash of a swap. Any ideas on how to isolate this function?

most of the cluster functions are BUS functions, so you'll either need something that can translate to a pulsed signal, or install something in-line with a coil to generate such a signal.
