JD990 hydraulic hookup question

[Rustyrat]

I have a JD 990 with an 8B backhoe. I have removed it and want to hook up a chipper. First of all I am not sure which hookups to use. At the back of my tractor there is a metal plate with 2 connections, the female on the left says "To Remote Valve". The right fitting says "From Remote Valve" and has a short hose with a male end that fits into the left connection. I assume that is used when there are no attachment on the 3 pt hitch requiring hydraulics. There is also a male hydraulic fitting 8" below the "From Remote Valve" that is a male. I use this lower one and the "To Remote Valve" fitting for my backhoe.
I am also not sure which ports to use for my chipper. Where am I supposed to attach the 2 hoses from the chipper? I am not sure if I use the same ones as the backhoe or if I only use the top two. The female chipper hose fits the lower male fitting.
The "To Remote Valve" is a female that says Parker 60 series
The "From Remote Valve" has a short hose with a male end
The lower one is a male, the rubber cap says Pioneer 2309 (I think)

The chipper male hose says "Italy Stucchi M BIR 12 NPT B05
The chipper female fitting says "Pioneer 4050-4. This one fits the lower male fitting on the tractor.

I would like to get whatever adapters I need without changing the fittings on the backhoe or chipper (the chipper is borrowed).

Here is a picture

Does the chipper have it's own valve?

If not, then you will need to add one to control it. The lines at the rear that your 'hoe was connected to is called the "power beyond" lines, and they have the full flow of the pump through them whenever the tractor is running.
