Some '98 cars actually have the plastic top engine and thus have the M1.5.5 ECU so you need to double check to be sure.

If you have an alloy top engine then you have the M2.10.4 ECU (in the passenger footwell under a hatch which is under the carpet). If you have a plastic top engine then you have M1.5.5 ECU (mounted in the engine bay on the Throttle Body with 2 large plugs going into it).
