Question:

I have tested the right turn signal and I am getting intermittent power going into the converter however I am getting constant power out of the converter resulting in the right trailer light to be light but not to blink. Please help.

I did not catch what vehicle you have nor what wiring harness you are using but if you are testing the turn signal wire going into the converter box and getting the correct intermittent signal but are receiving a constant signal leaving the converter box on the turn/brake signal wire then this points to signs of a faulty converter box. If this is the case then the wiring harness will need to be replaced.

For replacement, I recommend using the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector if available as we tend to see the least amount of issues with said converter box. If you can provide me with the year, make, and model of your vehicle, I would be glad to confirm compatibility. For example, the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118482 fits the following:
