I will try to get you pictures of the switches. I put the two switches over the lowrance unit on my z6. Hook them up through the fuse box.not sure how you would do the trailer lights,i guess you could run them off your parking lights when you plug your lights up. I love my blue water leds.. I got the switches from blue water, they also have a dimer switch but I just wanted the on and off switches. Its hard to tell from the pictures but the deck lights are really bright but not blinding. I wanted the lights so I could see what I was doing in early morning tournaments. The compartment lights really surprised me on how well they lit up the compartments. The only down fall is that you need to take you're time installing them. Its more work than you think. Lay them all out and if you get different colors make sure you test them by touching them to you're battery first. I put that shrink tube around the wires before drilling the holes the wires barely fit through the hole so I got a tight fit. Also on the live well. I ran the wire up the side and drilled the hole at the top of the live well and used Marine grade silicon, they had me drilling the hole at the bottom where the light was and I did not feel comfortable doing that. But you can't see the wire anyway. Oh one more thing be sure to buy allot of wire cause they do not send you any at all just about 2 feet attached to each light.. Hope this helps..
