Re: harness adapter
They don't because the demand is not there. It it was they would exist. Besides, there would need to be so many of them that the cost would be prohibitive. Take Yamaha for example. Do you think ALL Yamaha cables coming from the engine to control box are the same? A DFI engine set up for digital gauges and data are different than those for a carbed engine. That's just one example. Now do that for all engines from one manufacturer and multiply those by the number of engine manufacturers. If you still feel this is a great opportunity -- there ya go. Your chance to be the next millionaire. Fact is, if you need to make this conversion, by a junk OMC control box to get that connector, Remove the plug from the Yamaha harness and splice on the OMC making sure you have each circuit matched as required. Plug it up and go.
