There are 3 computers. ECU and Front electronic module under dash passenger side. You need to remove some trim and be a contortionist to get it out but it can be done.

Rear Electronic module in trunk inside right hand fender (looking from rear to front) remove trim and it is behind a bracket.

Then there are various modules that do different things including stopping you from swapping units from another car.

Good luck

Oh get a JTIS on ebay....very comprehensive and has diagrams showing you the positions of these electronis
