Front Offside Wing Indicator not working

Hi everyone

First off apologies for all the posts recently but I'm so close to getting Landy back on the road.

The OSF wing indicator isn't working on my 2000 TD5 defender.

I don't know if it worked when I got her as I basically stripped her down straight away (first schoolboy error). I then reassemble and repaired her which included clipping the wing harness to the inner wing and then bolting on the outer wing before testing it (second schoolboy error).

All of the other indicators work as they should. All of the hazards work as they should (except the NSF wing indicator)

So this what I did to investigate last night;

Tested the NSF front with a multimeter to make sure the multimeter works!
Replaced the bulb on the NSF - still didn't work
Tested power to the bulb holder - no power
Tested the wire to the bulb holder - no power
Tested the wire at the wing side of the wing - no power
Checked the fuses and they are all ok.

The only thing I haven't checked yet is the wire from the main loom to the wing connector.

Its the little things that are testing me now.

Any help or tips will be appreciated.
