help please wiring steering wheel buttons

[minimoss]

hi, some time ago i bought a d shape wheel with 2 buttons that i wanted to use for horn and flash the lights on my blade. i know the horn side is quite straight forward, just doing away with the current switch and connecting up to one of the buttons. but the lights side of it would like some back up on this please, im going to use 2 coil cables as used on 12volt accessories, aslso do i need to use relays. many thanks

Yes you most definitely need relays.

Is the car being built or is it already finished and is this a modification?

Anyway, the lights will already be on relays, I expect, so all you need to do it to locate the appropriate wiring to whatever the existing switch circuit is, and strap your new switch across the existing one. Won't work if there isn't already a switch, of course, or provision for one.


Need more info from you before proceeding.

Depends on what rating the switches have, some can take only a small voltage.
Personally I wouldnt have any live feed to the wheel, switch whatever you want on them via earth.

If you used a latching relay on the headlights you could use the one switch for both flash and Dip/high.

hi, the car is on an 04 plate and because the horn is on a switch on the dash and nothing to flash the lights with, its not an ideal set up, the buttons are non latching. i dont know if all westfields have the same standard set up. i think the light side of the wiring is standard, switch for side and headlights and another toggle switch to change from dipped to main beam.

Have you tried the WSOC forum, I expect there would be people there who would know the answer to your latest question right away.

hi, ok thanks, ive posted the question on the westfield car club.

There's a nice relay availble (from i think Hella) that is a headlamp flash / dim/dip relay all combined. Basically, if the main light switch is ON, then momentarily grounding one wire (via your steering wheel switch) swaps from dips to full (or vise versa), but if the main light switch is OFF, then it just gives a single flash of main beam for as long as you hold the button down. iirc, it was used on old volvo's (740/340 etc) might be able to turn one up in a scrappy etc??

That is the latching relay I'm talking about.
