Replaced my MCOR and now the cart will cut out at full throttle

I recently ordered an MCOR off Amazon for 49.99 for my 2010 Club Cart DS. When I replaced it the orange rubber washers (for weather protection)  and plastic ends on the clip in wires needed to come off for them to clip into the unit. I thought that was odd. Everything is working fine, but when I put it down to full throttle it cuts off. I have replaced the OBC, solenoid, speed sensor, and now the MCOR. The part number off Amazon is 102101101. I noticed while searching a web-site that the part number had a dash in it. I asked a local cart tech and he said it sounds like the MCOR may not be the right one for my cart. Also in searching a web-site I noticed that it said the one is for 2001 and up, then I noticed below in detail it was only for 2001-2004. What MCOR should I get? With everything I replaced the only item I believe it could be is this. My cart serial number is AQ1036-125073.

I would love some insight on this and will keep my business with yourself if you are able to identify that this is either the wrong MCOR, and you can ship the correct one out, or what to do. Thanks
