Does exactly what I wanted it for. I knew my car wiring was okay and that it was the trailer lights that were the issue.

J'avais un trouble électrique sur ma remorque et ça m'a aider à le solutionner. J'ai du faire plein de test avec des combinaison d'éclairage pour comprendre ce module. Des instructions seraient appréciées.

Nice quality and works well. I have four trailers and had my share of ground issues, brittle wiring and bulb issues. I should have had this years ago. It quick and easy to use.
