The pink wire should go to the brake warning light. This light will illuminate when the parking brake lever is pulled, or when the brake pressure shuttle valve is "activated". This pink wire is hot, as the circuit is completed via grounding through the parking brake switch or the brake pressure switch. There should be a gray wire that also attaches to the bulb.
