The 250D does not come with a fused power cable, only an in-line fuse holder. You can purchase any 12 or 10 gauge power cable to complete the install. The good thing about this size wire is that you will be able to use crimp connectors that are available at any auto parts store for a secure connection. Either use heat shrink to insulate the connectors or just purchase insulated connectors to do the job.
