The ones for my '3i loom are part numbers 85BG6911AA (Yellow - Fuel pump) and 81AG14N089CA (Red - Fuel injection). They are identical relays, just a diferent colour for ID purposes. The relay types are standard accross the board where EEC-IV is installed, just diferent colours for ID.
The fuel pump relay from MFi can't be used either, must be a spst item. The reason being that the EEC-IV controls the priming, whereas in MFi the fuel module provides a positive pulse to one pin to make the pump prime iirc.

what colour are the plugs that the relays connect to for the fuel pump and injection relay? i have a series 2 and trying to do this converstion, think i've wired into same relay (the big pink one), so i can change the relays to yellow ones (al long as they are correct numbers) but thats only the fuel pump relay, don't know which relay is the fuel injection one. Can someone please help??
many thanks
