Here is what the OEM PB kit looks like, it sounds like you have plumbed the loader in parallel and not in series.
You really should start your own thread and include picture of where your are hooking to for better help.

Now you know what parts to order and where they go.. let us know how it goes.
Thanks to KennyD for posting the figure and all the parts with numbers. He is an invaluable resource to TBN
Others who read this thread in the future, will have a leg up on solving their similar problems.

There is a plug you need to install in the rock shaft for every thing to work properly. I have the hydraulic flow path in my post about mounting an aftermarket loader to a 790. The pics are from a 870/970/1070 rock shaft and the 790 type but I will bet that you are having the same issue I had installing the loader. You need to make sure of the flow path of the hydraulic fluid to insure not over pressuring the loader system. I installed mine backwards (PB to supply and supply to PB back to rockshaft) on the original try and will have to repack the bucket cylinders due to the pressure that was on the loader with out the relief system that is in the rockshaft that controls the pressure.
