Just match all the colors up. There should be 2 white wires that are on the OBD0 distributor plug and only one on the OBD1 plug and an extra yellow/green. The larger of the two white wires on the OBD0 side needs to go to the yellow/green wire on the Obd1 side. Therefore, the smaller white wire on the OBD0 side needs to go to the white wire on the OBD1 side.
