tezzer , I would hook anything to that outlet after I seen what is possible by doing so , I bought a 300 not running for a parts bike, the grandfather had changed so many parts on the bike and could never get it to spark and gave up , while stripping all the wire loom and tape off the harness , I found the power wire to that plug had melted all the way back to the battery , after replacing the harness it cranked right up and that is now my son's 300 and a great running bike
if you want a power port , I like using those connectors , that look like a boat trailer light plug , except it is two wires instead of 4 , it is the same connector used on battery maintainers , so the battery maintainer plug can double as a power lead
