The Tow Doctor for the trailer side is # HM50928. The other one, # HM50918, is the vehicle side.

For the trailer side model it does not work if the trailer has LED lights. LED lights draw too little power for the tester to work properly.

You could test the trailer side by using a separate 12 volt wire and applying power to each function. If the function does not work doing this test you know there is a wiring issue.
