These are the plugs cut from a FACTORY wiring harness. Its Very Typical for these connectors to break or the rubber to deteriorate resulting in bare wires touching causing a no run/start issue. The Two wire Ignition coils should be very easy to resplice. One wires color should always be green/orange or green/black and the other should be grey in color. They used the simple oval style from 1991-1997 and then went to a complicated style in 1998-1999. Most everything from 1999 and newer used the 4 wire coilpack style. These MAY be a little harder for connection. Would be simple to copy off the old connector if possible. If not you may could use www.charm.li for a free wiring diagram. I have not added the renix style yet or the 99+ 4.7 V8s. These should work on 5.2/5.9 V8s in dodge and jeep as well.
