Will this fit this Harley 14 pin connection? I have bobcat S650 7 pin ob loader machine....

This is for a Bobcat 14 pin.  Not a 7 pin.  You will need this.

I do not know which connector they installed on the broom so here are our controllers to choose from.  Here are the three most popular.

You will have to decide based on the CID connection.

Will that plug fit a JOHN deer 333e we have a 14 pin to a cid utopia fit a fast track cement mixer

Yes, but you need to move the ground pin.  JD uses all of the same pin locations as Bobcat and everyone else except the ground.  I always suggest that the owner should move it in the machine so it becomes universally compatible.  It takes 5 minutes.  You move pin A to B.  If you choose not to do this, then pretty much every attachment will need to be moved B to A.  Video #100 shows you how to do this.

I have a 6 pin need to adapt to Kubota 14 pin

No such thing as a 6 pin in this industry unless someone cobbled something together.  Send me a photo of what you have please.

I have a Erskine model 2000 snow blower and what to go on a Cat skid steer 257D 2014 year.what do I need to make his work

What connections are on each?  The machine?  The attachment?
