Engine bay wires rubbed through See pic

Hey all
Was doing my monthly oil and water check on my 01 TD5.

Ive noticed the 2 wires coming from a connecter plug under my oil filter and going over the transmission have rubbed though and are no longer connected to anything.(see photo)
Does anyone know what these cables do, as the car runs no worries.
im guessing they just illuminate the dash for low oil?
what do you legends think?

Yep, correct -.low oil pressure warning. Just trace back to RH side of engine and replace worn wire sections. It's part of the engine loom harness.

BTW, as far as I know, only one of these wires actually connects into the loom. The other just sort of hangs out there.

Easy, one wire is still connected the other which i assume rubbed though is the one which doesn't do anything at all! thank you everyone for you help! ill put some new sleving over the cables later today! legends!

I wouldn't assume it does nothing unless you are certain your low oil pressure light comes on when you do an oil change.
