ECU Help Please

Hi there, I spoke to you about it a few weeks back but havent had an update.

Looking for something compatible with my '95 GTO SR for a TT conversion.

Current ECU is MD310343 E2T61475 (with three green connectors).

Could you please let me know what year & part number TT Ecu to look for? Would you have one for sale that I can get my hands on? Do I need to change the wiring harness or can it be a plug and play?
