optional plugs on dash

[reg_c]

does anyone have wiring diagrams that show what the factory wires lead to behind the 3 switch mounts for optional extras?

cheers guys

I expect one is for the headlight washers that were standard in some markets. Our fog lights use one. There's also one on the console that was used for a "sport" transmission mode in some markets.

Depending on Country and model, the three slots can have:
- Headlight level adjust
- Front fog lights
- Headlight washers

Maybe there's some other options as well.. Not sure. What you want to do anyhow?

just the location of relays and wiring so I can mount factory switches for driving lights, fog lights and reverse/cornering lights

Fog light relays are in a box enclosure in the engine bay. An absolute nightmare if you're thinking of hooking into that. The wiring harnesses are wrapped up tight and access to the relay box is nigh impossible.

Just a word of warning on the factory switches. I bought a spare one so it would match my other two when I installed my air horns, but they are not like a standard switch. Firstly they are ridiculously expensive (I think it was something like $75/each). If you get the ON/OFF fog light switch and you're thinking of using it as a relay trigger just be aware that the internal light is incandescent (not LED) and draws too much power to then use the outgoing side on a standard 12V relay. You need to modify the switch internally (i.e. take it apart and potentially damage it). Lots of mucking around, not to mention the cost. Consider using the button blanks to mount a switch and using your own wiring and relays.

I bought a set of factory foglights, they came with the switch and the car was already pre-wired for them. Installation was very easy and no problems so far.

There are three blanks on the dash - one for fog lights (already pre-wired), one for alarm system, and one for headlight washers.
