Looking for one of these (attached pictures). It's a plug that pops into a circuit board on a Precor AMT exercise machine. Thanks for any help!

 

Looks like a standard Molex type of plug (perhaps MLX series). You need to measure the spacing between the pins, as they come with various spacings. Also, you have to look at how the plug is "polarized", that is, one plastic part has a flat surface on one side.
Try online shops like Digikey, Mouser or others.

EDIT: It looks a bit like this one:
