I'll let Moose the Zuke expert tell you about that, however on my Tohatsu/Honda they did NOT want to run the old power cables all the way to the engine. Strongly suggested to only use the ones already factory installed. I took the #2 power cables I had from the other engine, coiled up the excess and connected them to the factory cables with two single post connectors. No problems.
