Remote start stereo turn on

Why would you want the radio on during remote start? That's annoying. Plus, you park your car while your CD is on track 2, let's say. Now by the time your car is warmed up, the thing is all the way to track 7 and you have to go back. But anyway, pink and white let the engine run. orange lets the climate controls and power windows work. brown lets the radio and wipers work. Wire up a relay as floterr describes, to power up the brown wire, and then the radio will work.

that is a good question.  That would make it very simple.
