cheers, mike.
Basically they arent part of the engine loom, but they are identical standard 40a SPST relays (fuel pump and injection). FRST ones can be used if you want a factory look, otherwise just get some from your local motor factors, not expensive at all. Just make sure the terminal numbers on the underneath match.
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.
