Rear Fog Light Wiring

[andyborris]

My reading of the MOT manual suggests that a rear fog light on a 1994 manufactured (registered 2004) imported car only needs a warning lamp to show when on, it doesn't need to be wired into the lights in any way?

Thanks

eh??

[andyborris]

It can be switched on independently, without any of the lights needing to be on?

Surely as an MOT requirement the rear fogs need to come on though? IIRC it's only pre 1980 cars that don't need one....

[welshpug]

every car ive ever used has needed dipped beam on for the fog lamps to work.

and they need a telltale.

[welshpug]

very easy to do, single relay, use the switch to pull the switching side to earth, use the dip beam to provide the positive.

Thanks, I'm bypassing the broken rear light wiring loom (the break is up in the headlining and I can't be are**ed to take it down!).

Wouldn't mind so much, if I ever used a rear fog light.......

I guess its breaking where it enters the tailgate? I'd rather try and fix that than leave some exposed live wiring.

[andyborris]

You'd think, but no!

It's gone somewhere in the headlining, probably at one of the many connectors. It's a Delica with electric blinds in roof skylights and a ton of wiring and connectors!

Anyway, now wired to come on only when sidelights are on, which is how Mitsubishi wired it. Switch swapped for one with a tell tale, 'cos the dash warning light don't work now and a Dyno Label for the MOT man, very race car retro!

Correct - for MOT it can operate independentlyof any other lights.
