Ive got an 07 Manac spread. I want to put a rear dump valve in. I read different post on here about dump valve, but i guess each is different. Here is the schematic on the airline on the trailer. it appear all the air bags are connected. Any help is appreciated. I am going to use an electric dump. The box on the bottom of the schematic is the axle suspension weight guage.

It looks like you have a whole suspension dump valve already. I’m guessing the trailer dumps when you exaust the emergency line.
You will have to do some Replumbing to run a rear axle dump valve. Nothing major. The air line coming from the the front left bag to the left rear bag needs to be re routed to the right front bag. Plug the open port at the left rear bag. Now install the dump valve on the line running from right front to the rear axle.
