You mean a 1990 throttle body, right?. Here in the UK we had carbs on our Zuks up to around 1994. From what I have read over the years 1990 was a changeover year for EFI on Track/Kicks. The 1989/90 models had a slightly different EFI set up with a different TPS and possibly a few other differences too. As I understand it the 89/90 ECU is not compatible with the later system. You will need to determine what setup you have, the 89 TPS is just a 2 switch set up for for idle and WOT, the later models have a variable resistor.
