Need a little help with finding a hot wire

I need to get 12v from a wire under the dash that's only hot when the ignition key is turned on and the engine running.... I've only found two (a red & a blue) both of those are on what I think is the brake assist module / switch located on the upper part of the barke pedal... When I try to use either one of those I get a ESP/BAS warning light so I need to find another source...

Anyone know which wires / color codes have 12 volts only when the key is on and won't screw up the computer?

Thanks in advance
