Guys - need your help/advise with one thing on this. ATM my curcuit runs off a 12v from the cigarette lighter, is there anyway of getting it to only turn on with the sidelights? So it only turns on with the main dashboard lights? I'm pretty sure some people here have got neons etc to turn on with the dash illumination so maybe?....
Also - IF anyone is good with circuits please pm me. Need to make sense of the datasheet for a chip or two!
You've pretty much answered your own question, where your current cable runs to the cigarette lighter, instead find the cable that goes to the stalk and becomes live when the sidelights are turned on.
This cable can be found in a variety of places to "T" into, it goes to window switches, dash clocks, heater control illuminations, etc, just use one of those.
