Very easily if you have the dealer do it. I believe the BX has enough oomph for one rear remote. Others may have more specific information - your dealer surely will.
You may want to consider posting this topic on the Hydraulic forum of TBN.
Does the BX25 have rear remotes for the BH? Are the valves before or after the disconnect? This cylinder worked out well on my BX2660. Used 1/4" hose and could use a little more restriction.
I asked one of the guys at the service desk at my dealer about it and he said that anything is possible, but had never heard of such a thing. Maybe greener than me?! The remotes for the BH on the BX25 are on the BH, therefore, they are after the quick connects. The BX22 TNT job was amazing. I wouldn't consider myself qualified to create that hitch. Thanks for the help guys.
