2) Pin no. 27 (brown/yellow) needs moving to pin no. 45
3) EDIS Module pin 2 (blue/yellow) may now be disregarded as it is not used by the 0FAC ECU (pin 28 on ECU).

There are no MAP sensor pin changes as the OFAC MAP sensor is the same plug as the 2i MAP Sensor, so just plug and play.

But... only on some conversions it seems!
Some work plug and play and others need the above doing, maybe there are some subtle differences in the ECU/loom's of different years I don't know?! But I guess if it doesn't work one way then try it the other! lol
