Main beam wire

[bloat]

Hi all what color is the wire for the main beam so I can wire my spots into the high beam at the steering colomb end cheers:thumbs

As I'm in Bristol (at the moment) and my Terrano is in Spain I can't come up with the main wiring colour code, but what I will say is that my T2 came with spots already fitted and, to my mind, wired as they should be. The main beam connection has been picked up from the loom about halfway down the drivers side wing. At that point a 4 terminal relay has been fitted, so that main beam operation simply closes the contacts. The spotlamps are wired to the relay so that the only extra load on the car wiring/switching is the closing of the contacts. The power for the spotlamps themselves comes from a permanent live (direct from the battery if that is the only place a permanent live can be found), through the relay contacts to the spotlamps.
Doing it this way means there is no need to make any connections inside the car and you are not going to overload your existing main beam wiring.
As you can probably gather from my rambling explanation I am not particularly technically-minded, especially after my third glass of a very cheeky Shiraz, but I am sure that better informed members will be along to put those ramblings right.

Can't remember the wire colour now as it was 7 years ago & don't have that T2 any more but I took the feed from behind the drivers headlight to the relay which must have. IIRC some people took the feed from the N/S headlight & had probs with headlights/spot lights going dim but can't remember why:doh

Both posts sound advice. But don't forget a fuse.
There is also a Workshop download showing how to wire them.
I wired mine from the headlight directly, but I forgot which side.
As Sweety says it does matter, and this is the reason why...
On my mav, when the side lights are on and the engine is running, the headlights are dim, because the headlight bulbs are wired in series.
When on full beam, they are wired in parallel.

Taking from the wrong side means the voltage will be too low to pull the relay in.
So test it with a multi meter.

Hope it helps.

best regards,

Cheers rustic:thumbs just couldn't remember why they dimmed

Should have also put, the relay has it's own 15a fuse!

Thanks for all the replys I have bought a wiring kit so everything is there fuse relay etc but I just don't know what color at the main beam steering colom is, I'm not particulary good with electrics but thats the only thing left lol I have put the switch in so I can have them off, (when I have the covers on) or on with main beam when covers are off. :thumb2

Just so you know, that is an MOT fail if you wire straight to main beam

In the early days of the Ford Cortina Sport, Mk IV the spots were wired in with full beam from new.

So what has changed, mine are wired on with full beam too, but also through a separate switch, which is magically off at MOT time.

I thought it was fog lights that were illegal on full beam...:nenau

It's not an MOT failure for Spot Lights to be wired to the main beam, with out a switch. It's the way practically all production cars with built in spots do it.

Fog lights and driving lights are different, but since a Spot light must only be used where it is safe to do so with out causing dazzle to other drivers, they can only operate on Main beam, and must not come on at any other time.
