You need to compare the 'pin-out' to the C100 of your '92 to whatever you have the opportunity to buy.
8A-202-13 gives you that 'pin-out' for your '92.
I didn't bother to compare to '90. It's something
you need to sort!!
If the '90 was from a C60 car it would require modifications to be used on any C68 car. Here is the '90 C100 'engine side'. You need to compare cavity population and each circuit mentioned in likely both FSM.
