I am despirately hoping that one of you Jeep guys knows how to swap a Jeep V8 into a Jeep with an inline 6. My problem is that I have a 1995 Jeep Grand Cherokee Limited with an inline 6 that has seen much better days and I need to find out how I can put a Jeep V8 from that same year of vehicle into my Grand Cherokee in place of the 6 cylinder. My motor is done dealing and I already have the V8 to put in it, but don't know what kind of wiring and plumbing I have to do to get this to function properly. Please help me as much as possible as this is my only vehicle and it just took a shit on me last night on the way to Christmas Eve mass. Please help.

You are in way over your head. You'll need a wiring harness, ecu, fuel lines, pump likely, new exhaust, new powersteering, and coolant lines, and likely a different tranny, bellhousing, or adapter. By the way you phrased your question, I'm guessing you want to keep it smog legal, and you do not know much if anything about engine swaps. You would probably be better off buying another rebuilt engine, or paying someone to do the swap for you if it is your only vehicle.
