hi all
i have read that i can swap the wire from A20 (EVAP purge solenoid) to A17(IAB) on a p72 obd1 ecu to activate the IAB's i was wondering if anyone had anymore info on this...
does the p72 need the evap purge solenoid?
would it not be better to run a hard wire from iab to A17?
i am running a B18C4 uk spec with D16Z6 loom from ecu to engine.
thanks in advance for your advice!
mike.
