Oil pressure warning light, any ideas?

I am afraid I left the oil feed hose uncovered and unprotected. unfortunately, I thought it will be OK to screw the bolt back to the turbo without the hose as the only protection on the oil system.
It that's the case... primming the turbo (topping it up) would be sufficiant?
I did the manifold on mine a few years ago and that is just about exactly what I did with no issues.
 
@Menash have you unplugged the oil pressure switch to check the oil light goes off (don't start it, just go to key position 2)? If it doesn't go off, you have a wiring problem. If it goes off, the switch could be faulty.
 
An intresting update....
I checked the switch and found it's connected to two wires: brown one which was disconnected (just 25 cm of wire with dead end) and yellow one witch I unfortunately accidentally close the screw behind the head on it (the screw witch hold the metal pipe behind the head while I replaced the cone coolant pipe). When I fixed the yellow one the light disappeared.
My question is- is the brown one supposed to be disconnected at one end?

Well done on sorting it! However, the wire colours are interesting - the connector should have one black wire (unused) going to contact 2 and one white/brown wire going to contact 1, the switch. Anyway, only one wire is used.

Edited to correct contact number!

If the switch is faulty or wiring unplugged or damaged it defaults to light on..
NOt exactly, if the switch is unplugged the light will be off all the way unless it's a short to earth on the circuit cos the light comes on when it gets earth through the N/C switch then goes out when the pressure opens the switch
