Just so ya know, some models dont have the purple at the radio harness....you'd have to go behind the glove box. Its a purple-white wire with silver and its hooked on the pcm

Just to remove or even add to the confusion, the baby ones have a purple going into the inst panel, obviously for speedo, also PURPLE / white was the original colour, here you could always find it either behind glove box on one of the management ECU's or loomed up with the radio feed and that's been the case for about 8 years. Just remembered the baby is the Yaris. Asking for reversing light is a bit cheeky, it will either be on a gearbox switch esp if auto or at the rear and use a bloody meter! What's MIC wire please.
