The cold side of the brake light switch on your 2014 Chevrolet Express should be a white/blue wire but you will need to test this with a circuit tester before making the splice. The correct wire will only have power while the brake pedal is pressed. The wire can be spliced into anywhere between the back of the brake pedal and body control module (BCM) but I don't have an exact location for this.

Please note your van may already come with this wire ran for you taped and tucked under the driver side floor mat up towards the firewall (see video) so I would check this before making the splice behind the brake pedal.
