Quick picture/explanation request (blower motor)

Hey guys, just want to say thanks for all your help thus far.

Stereo & sound system are in:)

Unfortunatly, my ignition cylinder is going, so my radio & blower motor often times stop working once the car is on (however they do work in acsessory).

I want to rig up a connection between yellow / red wires on my headunit for constant power, and an external switch to the blower motor to turn it on off.

Headunit i'll figure out, but is there any chance you guys have a picture of where the blower motor is, or could take one?

If not, could you describe it to me?
