I already have another reliable car, so I'm looking to do something to my tc. Apparently the 2gr would be an almost direct bolt in, my questions are with the fuel and wiring. Using a 2gr ecm of course, what electrically needs to be connected between the tc to the 2gr ecm? Gas pedal, fuel pump relay, speed and rpm from combo meter, anything else? And is the stock tc fuel pump powerful enough to supply the 2gr?

I know multiple people have swapped a 2gr into their mr2, so I'm trying to learn the smaller details, like getting the tach/speedo to work with the new engine.
