I was concerned before installing it, because I have a ShowChrome fuse block, then no idea how installation was done, and having all the wiring for the trailer, well, once I removed the seat, I found everything well done, I was able to install the module as explaine on your video, only challene was to reove the OEM connectors clamped at each side, very tight space and triky to remove them to disconnect adn install in line the module, other than that everything was easy, works perfectly, I very happy with this upgrade, I strongly recomend this devise.
