2002 motor swap in my 96 gt question

The 2002 has COP and an electronic cluster. If you were to use the 2002 motor harnes, then the body wiring harness, PCM, cluster, fuse boxes, would all have to be changed as well.
If you goal is a straight forward swap, the motor harness from the original car will have to be used.
The 96 style coil packs is the easiest. However, it is possbile to rewire the 96 harness to use COP. There is a link on a Cougar/Thunderbird site (don't know).
I would think if the sensor electrical connection is the same, then the sensors are interchangable.

Yeah, just use your existing harness.
The 96 uses two temp sensors - one for the PCM and another for the temp gauge - and the 2002 only uses one so you'll have to find a location for the second sensor. If the 2002 intake manifold has the newer style aluminum coolant crossover tube on the front of it then there's a spot already there for it by the thermostat that just needs to be drilled and tapped. If it still has the older all plastic intake then you'll need to either swap it to the updated PI intake (which you should probably do anyway) or rig up a kludgey t-fitting or find some alternative location for the second sensor. The two sensors operate differently so you can't just split the signal electrically. I can't remember now when they started putting the updated intakes on but I think a 2002 should have it.
As brought up in another recent thread, the '96 has a low oil level sensor and later Mustangs don't (I'm not sure when the stopped though) so if the 2002 doesn't have a spot for that, you may want to swap your 96's pan over to the 2002 motor.
I've read through the COP swap on TCCOA and I don't think it's worth doing except from a strictly appearance standpoint. Apparently, spark voltage is much less than with the stock coil-pak setup - the PCM must not be able to drive the COP properly.

OBTW; it is possible to relocate the 2nd temperature sensor should you not want to drill/tap the intake manifold (or not want to replace the plastic intake manifold). I believe there is a water jacket boss/plug just below the freeze plug on the right side of the motor.
Create a wiring extension for the 2nd temperature sensor. Remove the the plug and put the temperature sensor in its place.
I bet someone will find/post the link with more detailed instructions.

ok thanks for the reply's.I gotta start the engine swap soon as I need to be sure this engine is good before the 60 day guarantee runs out on the motor,keeping in mind that I will be working exclusively by myself(no extra pairs of hands)I have yanked motors before by myself, 5.0s and 2.3s it just takes me longer,and the excess time is compounded by the size of my garage(tiny) and all the hours spent at my regular job.basically I will have to pull the motor and then move the car backwards out of my garage with a comealong since there is a decline in the driveway pitched towards the garage.I will also have to pull the automatic tranny from underneath.but in any event ill get er done.
