Volvo L50D quick coupler swap from donor machine

[trip]

Hello, I have a Volvo L50D loader with a 3rd valve but no quick coupler. I also have a Volvo L50B parts machine that has a bare Q/C, brackets for hoses, the electronic/hyd controller that is bolted to the left side of the machine where it articulates (unsure if its good) and wire/switch to the dash. I do not have the hoses (dried up) and the two way piston w/locking pins that mount inside of the coupler itself. Questions: When I look up the piston it shows C, D, and E models (not B). Can I use a piston and pins from a B, C,D and E from a 50-120 or only a B. Dose the L50D have a place in the wire harness to plug and play a coupler ( Had a Deere 644H 20 years ago that had the plug in the harness for the coupler/ made it easy). Any advise on what else I would need and has anyone heard of a aftermark kits (besides the coupler itself. I plan on visiting a salvage yard this week to see if they have some of these parts, just don't want to buy stuff that look close buy doesn't fit. Thank you in advance.
