To troubleshoot your trailer wiring, connect a jumper wire to the connector pins and the continuity tester to the system’s sockets. A continuity test helps you see if there are any broken wires. Select a color of wire in the socket, and find the same one on the connector front.

Why is my 7 way trailer not sending 12V?

The issue is that your truck is computerized even at the 7-way. It can sense when a trailer is connected based on the voltage draw so it won’t sent a signal for 12V when using some testers, especially LED testers because there isn’t enough of a power draw.

How do you connect a trailer to a 7-way?

The system requires a power draw on the 7-way and then holding the brake pedal for about 3 seconds until your dash registers “trailer connected”. At that point, the vehicle will deliver the 12V power to your trailer connector and not before.

Do you need amperage rating for trailer connectors?

The sockets themselves don’t have an amperage rating so you will go by the draw of the things drawing power. In order to figure out what the lights are drawing you could connect the trailer to the tow vehicle and turn on a function while testing the trailer side wiring behind the connector with a meter to see what sort of reading you get.

How can I tell if my trailer has 12V power?

At that point, the vehicle will deliver the 12V power to your trailer connector and not before. I recommend using a circuit tester like # PTW2993 to test for the 12V power once you get that “trailer connected” message on the dash.
