Hahaa Yes it seems easy to do! I had a lot of things listed on a local garage sale site on FB, with lil luck, made a few bucks here n there. But this is so much more fun!! I deleted all of them, and am starting to move them to this site :)
Im really not sure, electronics are not my thing lol. But I just took some more pics of it for you. I will put them up shortly. It doesn't have a diagram, but it does have a few labeled wires. And it worked when we took it out of the car a yr ago. Since then it sat on the top of my computer stand.
