[QUOTE="RangerRick, post: 428756, member: 19360"] [USER=18629]@Flyer58[/USER] the 4BT is the simplest of all Cummins motors to install in that it just needs ONE WIRE to run. Since it's all mechanical injection before computers became involved, you just connect the fuel shutoff solenoid to either the fuel pump relay power in a fuel injected YJ, (1991-1995.5) or better yet, use the ignition coil "hot" wire for it. That's it! The alternator can be hooked up depending on which you have as conventional if it is a Ford, GM SI style or ND Japanese type. Easier than pie. Now if you have the 2.8L or one of the ISB 3.3 or 4.5L electronic type Cummins motors, then it becomes more involved like doing a late model EFI gasser swap. RR [/QUOTE]
