Looking to add 14 pin connector to 7753

[Onfoot]

I want to run a 6 way dozer blade with my 7753. But it does not have a 14 pin (or any other) connector. So I am looking for connector harness and associated hardware. I have 'cobra' joystick tops--each with two rocker switches. So not sure if these will work with 14 pin controller or if I will need new control tops for the joysticks. Also not sure if 7753 parts for the connector would be the same as 753 or other models. Anybody parting out a relevant model?
