Good 12V source when ignition is on ???

[nrgetic99]

All,

As I now have a host of 12V powered do-dads in the X, I would like to turn the 12V outlet in the passenger footwell so it is only hot (live) when the ignition is on.

I will essentially interupt the power supply with a relay that only makes contact when the ignition is on.

I know BMW in their infinite wisdom uses multiplexing and bus control in our cars so you cannot just go finding a 12V ignition source as it may throw codes. set off dash lights etc so.... can anyone give me a safe +12V ignition controlled source in the front of the vehicle ?

If push comes to shove, I could use the purple wire in the multiconnector by the battery but that just makes the whole issue much more complicated.
