My 64 Dart the two cables follow the same path as the speedo cable. The front most cable is the push button cable and routes out of the firewall, jumps over the exhaust and enters the front of the transmission. The rear most cable is for the parking pawl. It follows the speedo cable from the firewall down under the floor of the car and sits in a cable bracket that is part of the floor. This bracket stops the cable from sagging.
