There is no automatic way of uninstalling the Sitecore Connector. It has to be done manually both on the Sitecore Content Management website (marked below with green) and directly on the server hosting it (marked with blue).
Be cautious: you are removing items and files, always do backup beforehand.
Because every Sitecore instance is different there is no way of predicting all the possible issues that can occur during this process. But this guide should give you solid understanding of what is the best order to delete or items and files related to Sitecore Connector. While removing items from Sitecore always use ‘Remove links’ option (but sometimes it is necessary to use ‘Scan for broken Links’ between the steps anyway). All the Items paths precede with database name (master or core). File paths are relative to the main Sitecore installation path on the server.
Verify that none of your items inherits from XtmConnectorBaseTemplate (more details below)
Verify that none of your items is in XTMWorkflowState (using Workbox details below)
