    Here is the way I would connect your trailer if it was done on a new trailer. the way you manage to connect it on your truck is up to you.

    Oh I forgot, if you want to go this route you may need something like this if you used the same type of junction box in the front.

    I just need a four pin, my question was really just connecting to two switches in dash. I have at least one unused and will add a second so they are together. These will operate the trailer lift axle and the trailer rear axle dump valve. I have gotten all I need to know by now, but thank you nonetheless.

    Since you should not need both functions at the same time, are there any on-off-on switches so you could use lift on top and dump on bottom?
