Dodge Trailer Park Lights not working?

TRAILER PARK LIGHTS NOT WORKING

2003 Dodge ram 2500 cab with 5.9L Diesel engine.

The Park light for dodge truck is working fine but trailer park lights not working.Trailer is factory wired.


HOW TO START TROUBLESHOOTING THIS PROBLEM?

Start with fuse,first check the fuse controlling trailer park lights.Its a 20amp fuse.
If fuse is shorted,then replace the blown fuse and it will work.
But if fuse is checked ok,then inspect the trailer plug connector.If all other brake lights and tail lights working for trailer and only park light is not working then trailer plug must be fine.But still remove and clean the trailer connector.
Also test the park lights terminals on fuse to see if has any voltage.

HOW TO TEST VOLTAGE ON PARK LIGHT FUSE?

It has to be done with volt meter.
You can also use test light.
NOW with that,
Ground the alligator clip of the test lamp or the black voltmeter lead, whichever you're using. If you're using a meter set it to 20v DC.
After that,
Turn the park lamps ON and use the red test lead or the test light probe and touch each of the two small open terminals on top the fuse. See if the voltage is there on one, two, or no terminals have voltage.

IF you get voltage on both terminals then continue further troubleshooting as mentioned below.

Go underneath the vehicle.You will see two electrical connectors.One is 14 way connector and other is 8-way connector. There just behind the left front wheel, behind the wheel well liner.Yow will see the  large rectangular connector. You have to view 8-way connector.There you locate black/orange wire. On the back side of the connector toward the rear of the truck, pierce the wire's insulation and see if there is power there with the park lamps on. 
Either the wire is bent or its got loose or dirty.Properly inspect the black/orange wire.

After testing is done seal the hole up with silicone,electrical tape, etc.

FINAL RESULT:

Thanks.
Orange/black wire was loose and reconnecting it solved the problem.The trailer park lights are now powering up.

This details will help.
Thanks.
