Jeep CJ7 help

My uncle is moving out of state and wanted to know if i wanted this old Jeep CJ7 that sat out back his house. He claims that it ran when he parked it there around 3 years ago but says that it needs a new computer to run. I was wondering if there is any way of wiring around the computer to at least see if it will roll over. Ive seen on some other sites that it is possible by splicing some wires together at the distributor but im not sure where to start. Im not sure on year but it has a 4 speed transmition with a carborator v6.
