Hi there,
I am in the process of cleaning up my wiring loom, and in the processes I'm removing most of the tape that holds the bunch together. I noticed a strange looking bare wire in the ECU plug as shown on the photos below, I was wondering if this is a standard wire or something someone has hacked in at some point. It looks oddly genuine, yet weird at the same time as it's left bare. Should I just tape this back up as is?
To highlight, most of these wires go to either ground plugs, or to the flywheel sensor. The other sleeved wires end up in the main loom.
Just for reference, this is the ECU:
