I replaced all of my white Tamiya connectors with Deans connectors, but if I ever need to send my electronics in for repair or replacement I would DEFINITELY install a new Tamiya plug first. [] I don't know how strict they are, but if you alter the unit in any way I'm pretty sure that it does void the warranty. Make sure that the lead looks stock by soldering it to the terminal where the original lead was connected, rather than just replacing the end.
