Steeler

I have a 2001 Sundance Altamar and I need to replace the plug-in connector on the main board related to the flow switch and temp sensor. I have many problems with errors related to this connector. Can someone tell me where I can find a parts list or where I may be able to purchase? I now have a FLO error and I am sure it is related to the poor connection. I just replaced the Flow switch in the last few months. Usually by wiggling the connection around I can clear the error but inevitably one of the errors returns.
