I have this exact model CUH-1200. I cannot remove the connector from either the motherboard or from the power supply (the latter seems more logical), even when applying all my strength. Is there some reliable way of removing the connector? Someone recommended "[t]he plastic fuse-puller that comes stock in most 90's+ vehicles". I do not have a vehicle from the 90s standing around though. Is there some specific tool or technique that can help?
