What’s this wire for?

[Jamboobone]

Hey guys,

I’ve been having intermittent dramas with my main EFI relay in the fuse box. I opened it up today and noticed a red wire with grey trace had been cut/separated.

Does anyone know what this wire controls? It came from terminal 1 on the relay if that helps.

TIA

Pin 1 of the EFI relay is the brown wire and should be a hard ground. What appears to be cut is pin 3 which is the logic from the ECU to energize the relay.
All this info is in the EWD that you're looking at.
