Identifying and accessing turn signal wires at column

[Neroado]

I need to identify which wires coming from the steering column are for the right and left turn signal. I need to access the turn signal power prior to the flashing circuitry, which I assume is part of the BCM. In other words, I need constant power on for each direction when the turn signal is activated, not intermittent or cycling power, such as flashing or sequencing.   

 

Also, if anyone knows what the most accessible spot to gain access to those wires is, that would be helpful.  I'm also assuming that the turn signal switch is controlling the positive side of the circuit with low voltage to the BCM.  I'm planning to use this switched power to activate a relay, so low voltage is fine.  If that's not correct, that'd be helpful info also.

 

Thanks,
