Driving tips ground. Do not connect safety chains to part of the vehicle other than the safety chain hooks. 2 1 HS8013BB 1) Hitch ball installation point 2) Hooks for safety chains 5. Use only a hitch ball that is appropriate for the ball mount and your trailer. The hitch ball must be securely installed on the ball mount. 6. Connect your trailer to the hitch ball. 7. Connect the trailer and the hitch with safety chains that will hold the trailer's maximum gross weight. The chains should cross under the trailer tongue to prevent the tongue from dropping onto the ground in case it should disconnect from the hitch ball. Allow sufficient slack in the chains taking tight-turn situations into account; however, be careful not to let them drag on the HS8015BA Hitch harness connector 8. Connect the hitch wire harness's black four-pin wire connector to the towing trailer's wire harness 9. Confirm proper function of the hitch wire harness by individually activating the brake, right turn signal, left turn signal, stop, and parking lights on the trailer. 8-24
