Your 'key' communicates with the ecu to see if they match. So a different ecu won't work. You need to follow the procedure on this site to get it working:

so this is it?
ECU Swapping with Immobilizer 2 Posted 24 Jun. 2003
Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk.
Immobilizer II:
The immobilizer will prevent the car from running without a matching key microchip. There is a symbol in the instrument cluster showing a key inside a car. If a new (or different ECU) is installed in the vehicle, the immobilizer will prevent the car from running and will cause the symbol to flash. Here is the procedure to introduce a new ECU to the instrument cluster. This must be performed each time ECU's are exchanged. This does not apply to installing a "chip" in the same ECU that is already aligned with the car.
Immo-3 knows your car's VIN. Access 17-Instruments (or separate
25-Immobilizer on vehicles that are set up that way) and look at the first "Extra" field.If you see something like: "Immo-ID VWZ7Z0W0648696" You've got Immo-2 (or maybe even Immo-1 in earlier non-US models).
If you see something like "WVZKB58001H231169 VWZ7Z0W0648696" You've got Immo-3. The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.
1.. Install the new ECU in the car [Select] [17 - Instruments] [Adaptation - 10] Leave channel at "00" [Read] [Save]2.. [Done, Go Back]
[Close Controller, Go Back - 06] [Exit]3.. Turn ignition OFF for 15 seconds. Start vehicle.

As long as they are the same part number.
Strange my fathers '95 (euro) has one. I don't think your going to break anything as long as they have the same partno. etc.

Or should I add, not here in the USA.
Hello again, I stop by a impendent shop yesterday that only does VW. They told me that before I swap the computer that they would need to plug into my car and check the range of my Throttle body. He said if I just plug it in my car may never start again even if I unplug it and plug in the original computer. have you heard of this? is this shop for real or they trying to scare me into buying a brand new TB? Please let me know any thoughts/Ideas.
Thank You in Advance.

Sounds like a bunch of crap.
There is a throttle body adaptation procedure that they might be indirectly referring to but I can't find evidence that it applies to a '96 Jetta. I think it's only on newer cars. But the car wouldn't be unstartable...it'd just idle poorly until the adaptation is performed.
Here's some info. Maybe it might apply to a '96 after all.
I changed the battery in a friends Golf and it lost adaptation. It just idled poorly and stalled at intersections for half a day, then corrected itself.
