The first thing you are going to want to do is test the trailer wiring harness on the vehicle to make sure you are getting power at the pins for the trailer connector. If you are not then I would need to know what trailer wiring harness you are using as well as the vehicle in order to troubleshoot further but the ground and fuses will be a good place to start.
If all is good on the vehicle's trailer wiring harness then I recommend you check the grounds for all of the lights on your trailer as well as the main ground for the trailer connector. I also recommend that you check all of your wiring to make sure there are no shorts. The stop and turn signal circuit are usually green and yellow wires.
