As I'm fitting twin 40 IDF's I have no need for the missing fi system including the extra wiring that would go to the relay board in the engine bay.

Is there a straightforward way to remove the no longer needed section of loom, either by rerouting bits that may be needed elsewhere or simply removing altogether?

Theres a 4 pin plug on the relay board pull that out with associated wiring,thats that gone ,then proceed to the tech article section on here and jumper an earth off the relay board so you can run your low pressure pump through the existing FI relay,this is the best and only way to go.
Good luck

There was no relay board in the engine compartment when i bought the car. All i have is the wiring on the main loom with the multi pin plug on the end.

You'll need the *relay* board. Also, voltage regulator anyone?

I have tested relay boards and voltage regulators. PM me for details. If I can get them in a padded envelope the shipping will be about $26. I would want $65 for a relay board, relays, and voltage regulator.

You need the board, voltage regulator, and some of the relays, as well as an engine wiring harness. Bruce's offer is a very fair deal.

So it would appear i need to do some reinstatement work that had at some point been removed.

A little digging around and i found a diagram showing how to jump the relay board to allow the use of the existing original fuel pump wires ( which i'll run up to the front where the new pump is going be be fitted) and make use of the voltage regulator to avoid having to wire in a custom installation.

Thanks for the help, Bruce as per my pm i'll be in touch shortly to arrange this and some other bits.

If it wasn't for this forum i'd be
