You will need b-series driveshafts. Think the d-series are little bit too long?

The d-series EK ecu & plug is different. The plugs themselves almost look like the obd1 plugs and there's only 2. You will need to get EK4 loom for direct plug and play. (with a b series obd2 ecu of course) Also with obd2 ecu's you will need to disable the immobiliser. Theres a DIY on this forum by ECU-MAN that shows you how to do. Pretty straight forward steps.
