Can someone tell me where this temp wire

[bimmerboy73]

Is supposed to go?

Installing a new AC temp switch as sensor wire (assuming that's what it is) as the old one broke when I installed a new becker a while back.

Just drill a hole in lower right side of the box facing the passenger and stick into the evaporator. The hole is hidden behind right side squirrel cage fan.

Thanks. Much appreciated!

this is actually not a wire but the temp sensor probe which needs to be close to your evaporator to sense if it freezes up.
@HB Chris 's instructions are right.

Put the probe into position and test-drive the car running the AC to see if it cycles as expeted - the switch will turn on and off at an interval. You want to have the probe at a spot where it picks up before the evaporator freezes, but you do not want to cycle on/off every minute, so this might require a bit if testing before finding the right position (depth).

Do this before you fix your front plate and console sides.
