Anyone able to identify this connector? (Behind fuse box)

    Aah cheers.

    I found a military wiring diagram that shows the red wires are for the sidelights front and rear but I can’t find mention of the plug. I did wonder if it was somehing to do with the nato switch, thanks :)

    From memory, it was the sidelights / rear lights that didn't work until the connector was connected.
    I suspect that the main loom on older military 90/110's Land Rovers was very similar if not identical to civilian models.

    I always remove the NATO switch and re-wire as per civy spec, it was very straightforward on the 90 as the main loom is the same as the civy item with a few ancillary looms on top (the FFR system is entirely separate). Don't recall having to connect the plug, I suspect it was already connected and certainly everything worked straight away.
    On Series vehicles (and my 101) it was different matter entirely, the loom is quite different (well, on the 101 for obvious reasons!) and some rewiring had to be done to bring it to civy spec. Very worthwhile though if you aren't worried about originality.

    I quite like the centre convoy switch tbh. And when I measured my headlight voltage (was thinking of making a relay circuit to power headlight straight off the battery) I found that I wasn’t getting hardly any voltage drop.

    Also everything electrical works so didn’t see the need to change it.

    Looking at the military wiring diagram and the civi digital I can’t spit that many difference except the convoy switch and I am sure the military one have more relays than the civi one but I don’t know why?

    holy thread resurrection....

    Was doing some wiring work on my 90 today and finally found out what this connector does.

    The military vehicle have a 6 way light switch in the middle of the dash, you can chose to have tailights on only, front sidelights and tail lights together, or headlights and tail lights and sidelights all together

    When this plug is connected together the front and rear sidelights all switch on and off at the same time regardless of the position of the military light switch in the middle of the dash, i.e the setting for tail lights only also switches the front sidelights (when this plug is connected)
    When this plug is disconnected the 6 way light switch functions as the military intended, i.e the sidelights, tail lights and headlights are all switched independently.

    Very minor discovery, but its been bugging me for 2 years lol

    @flat , this is a great discovery. We both have these connectors. The Q? is...are you going to run connected...or be adventurous and run disconnected? If only to confuse the MOT tester...

    In other news, re-wired the front side lights and indicators tonight. It's worth checking the wiring as four of the wires had split insulation hiding between the waterproof rubber grommet and the black insulation over sleeve...and further back, under tank tape, I've discovered burnt/crisp insulation on these cct wires :(
