How much motor electronics is in the Pajero 2800 TD from 1995?

Hello, a question to the experts: How much motor control electronics does a Pajero 2800 TD from 1995 have? Is the engine absolutely dependent on an electronic control system, or does it run without it? I am looking for an off-road vehicle without electrics, where the engine also runs, if it should fail, or if it is best not available from the beginning. Can someone tell me something about it? Thank you
