Yes the Chip does go into your ECU.
Your going to have to open the monotronic unit up, I took off both top and bottom of it and you will see that there is two boards one of the boards will open out of the unit like a book. On that board you will see 3 black chips and one of the chips will be sitting on a black conecter bay thing. It will be more elevated then the other chips. Just gently slide a screwdriver underneathe it and it should just pop out. Then just install your new chip, put it back together and reinstall! Should work if it doesn't you might have put the chip in backwards so make sure you put it in right the first time...
The ECU is located behind the glove box hanging from under the dash...
