Chris - It sounds like a crazy in depth endeavor but its really pretty simple. Since both motors are 1994, they are running the same electronics, including sensors, harnesses, and computers (provided they both run auto or both manual transmissions), everything will be plug and play. The connectors that Ford uses are keyed in such a way that only the proper wires coming from each sensor to the harness will fit together, you physically can't mess up connecting most of the sensor wires. As wood1 said above, grab a digital camera and take some pictures of the wiring - you can always fall back on these if you find yourself scratching your head. Personally, I always like to get a roll of painters tape or different colored cable ties, and mark each connector as I take them apart so I know, when its time for re-assembly, what belongs where in terms of wiring.
Following the chiltons or haynes should make the job a lot less complicated than it seems. Off the top of my head, pulling the engine consists of:
1) Unbolt Starter/Transmission bellhousing Bolts
-If Auto, you have to unbolt the Torque converter. You can do this by running a crazy length extension from the front of the vehicle into the starter hole and removing each of the 4 nuts 1 by one, turning the engine crank as you go.
2) Drain All Fluids
3) Disconnect air intake tubes
4) Pull the serp belt
5) Disconnect the AC from the engine bracket
6) Pull the Alternator
7) Remove Power Steering pump/ Connections
8) Unbolt the engine mounts
9) Disconnect all wiring connections that are made to the body harness
10) Remove any vaccum lines, taking a picture of them before you do so will be a huge help
11) Secure a chain or strap to the intake
12) Lift motor and pull towards front of vehicle
You can leave the main engine harness, ignition coil, waterpump/fan, idler pully, intake, and even throttle body attached and still pull the motor.
Hope this helped,
Jeff
