Since a 53 didn't come with an OD there is no factory routing. Route it in the most direct position so it is not kinked. You may need to drill a hole in the firewall if there is not one in the optimum location. The bracket below the solenoid holds the housing in place like a choke cable and the center part is secured in the drilled bolt on the arm. You may need to fabricate a bolt with a sleeve for the arm.
