on the loom, coming back from the ecu i have two wires that are attached in a type of black clip and from looking at a mates 16v gte this clip attaches to the main interior loom which is at the back of the actual dash instruments, i thought this maybe for the ecu warning light,
is this clip for the ecu warning light?
and if so, when not wired up would this prevent the car from starting? (i.e no spark)
any help on this would be very much appeciated
