Hey guys, my first post for Help  I’m not an electrician. I work in Electronics but mostly in Sales lol  I replaced all of the lights in my coach to get it a little brighter   And the dimmers don’t dim very well so I bought a bunch of low side dimmers tried to hook them up in the AI stuff and everything I learned told me I needed high side dimmers so I’ve got them here and can’t seem to get them work either I can get the lights to come on. I can get them to go off, but I can’t get the dimmer to have any control in them whatsoever and I keep getting told all kinds of different things with the research. I’m doing so I’m hoping one of you might be able to give me a firm idea on what I am not doing. I have a brown red and black wire coming out of the wall and that seems to be the coloring scheme for all the other dimmers in the coach too, which I am trying to replace them all   The dimmers I have are a three wire as well and they have black, red and yellow coming out of them   Appreciate any help you might be able to provide
