icemaker for Sears Ro 795.68039.215 frig

I bought a home with this frig in it. It’s equipped for an icemaker and I would like to have one. Sears Parts told me that item# was compatible, but when it arrived, the wiring harness pins on icemaker don’t match the plug in the freezer. freezer plus has a 6 pin plus and the icemaker harness has 4. Can an adaptor be purchased to fix this or do I need to get another icemaker and which one should be purchased? Any help appreciated!

Thanks!
