Fog Light Wiring

Hi, Hope that some of auto electricians can help. I am wiring in a set of fog lights and have been using a Halfords universal rocker switch. Everything works but it looks a mess. I now want to wire in a proper switch - part AMR 3751 - but this has 5 terminals - I have only 3 wires - anyone know which wire goes to which terminal.

Take out the switch which is working......unplug the wires(remember how they were) > check with a multimeter(setted on Ohm) between the terminals how they are opening/closing > take the new switch, do the same thing and plug the wires to the proper terminals in the sme sequence as on the previous one. Simple as that........thats what i'd do coz i'm not auto electrician

I have just done mine using a proper switch and used this



Just loop off another switch for the illumination

Thanks both - useful information. Will have a go tomorrow

Disco 2 switch is no good, its "momentary" not latching as the lights are switched on by the BCU completing the earth path.

A lot of the land rover switches are the same, The D1 fog switch is :-

PIN 1 and 4 are the "switch"
PIN 2 is "illumination"
PIN 5 is ground

PIN 3 is never used

Thanks Urban Panzer. It's the Disco 1 switch I'm using. Fog lights wired independantly without BCU
