89 heep wiring help

just picked up a 89 4.0 for $500. However, the wiring is all rigged cause they lost the key and everything is spliced into something and cant figure it out. I got a new column and know i need to find out where i can get a diagram of the wiring harness for the 89 4.0. Can anyone help????????????

Got a manual?

A chiltons book will have it, a FSM will have it too. I sure someone ewill post a pic or link of the diagram. But a manual would help ya out alot
