Looking to purchase a CAT skid steer 252b series, but it does not have the electronic plug in on the boom by the hyd quick couplers. My question, is there an after market or CAT product that I could install on the skid steer to operate attachments that have electric controls?
The easiest thing to do would be to use trailer connectors, they're available in 4, 6 and 7 pin commonly, other configurations if you hunt a little.
Google "Skid Steer Genius" then give them a call. - https://www.skidsteergenius.com/ Hint: You will need the machine Serial Number in addition to the model. Another option would be to find another 252B of the same Serial Number prefix that is being parted out and get the wiring & controls from that machine. The B models are now of an age where there ought to be quite a few around.
