158 plumbing on late model 4020

Hello everyone,
I'm sure this question has been asked several times, but where are the best places to plumb the hoses for pressure and return on a 158 Deere loader that is mounted to a 1970 console 4020? I of course do not want to take up any of my remotes to operate the loader. The older 4020 that the loader was on previously does not have the same fittings and locations to install as this newer model does. Pictures are great if someone would have any. Thanks in advance!
 
Picking up the pressure through a Power Beyond block and returning through the filter cover works the best,, tagging onto the pressure supply line under the platform is another way.
 
So I have heard I can get a filter cap already tapped and ready, I don?t want to cut or remove any sheet metal. Where can I put the pressure side other than power beyond?
 

If you choose not to utilize a PBY block for pressure you can insert a tee in place of fitting(key 2) at either location. Pressure control valve(key 7) is under hood next to firewall & other fitting is located under rear of platform that tractor operator rests their feet on.

Shown below are spec's for fitting(key 2)

A power beyond block is the best and cleanest way to go,it will fit in behind the left SCV. Jim will be in to post a picture of one after bit.
