The eeuro harness is intended to work with '89+ 900s, where there is a speed sensor on the speedometer. Although you can program this out with t5suite, the consensus is that without a speed sensor you're subject to some weird behaviors with idle and maybe even drivability. I think you'll want that speed sensor. On the eeuro harness, you will find a generally rectangular connector with four terminals (maybe only three connected, I don't recall) - that's the tach signal, check engine light, and speed signal. That connector would mate with the factory connector on an '89 900.
The car should start without this connector, although your tach won't work and you'll have no speed signal. If you smell fuel, I would suspect a bad DIC... do you know the one have is good? I would personally recommend adding a terminal on the eeuro harness for k-line so you can wire up an OBDII scanner or t5suite and see what's what - working on modern fuel injection blind is really frustrating. You could also use a noid light to tap into pin 2 on the DI cassette connector to see if it's getting a signal to fire (it probably is, since the injectors are). Noid light between terminal 2 (which is grounded to fire) and a 12v power source. Depending on what you find here will get you to the next step.
