On your 2012 Dodge Grand Caravan the brake switch wire you will need is likely a green wire. That is what it is on the same year Chrysler Town and Country. It could also be a white wire with a green stripe like in the video I have linked.

Test those wires to see if they carry the brake light only signal. Make sure the tester is grounded and the pointed end of the tester is penetrating the insulation so it can touch the copper strands inside.
