Hello does anybody know what the rear load center assembly does? I have a 2015 4044r that I added the 4th and 5th scv to. I do not have the 3rd scv. on the 4th and 5th valve body there is an electrical connector that would plug into the load center. I have it installed and seams to work properly but i have just tested it out and not really used it. Thank for the info you might have.
