Tachometer for Johnson o/b Looking to replace my dash and gauges this winter. Have seen the Faria tach with system check that takes the plug from my 1997 Johnson Oceanrunner to read out all the warnings sent from the engine. I noticed one ebay ad saying the tach was set up for "10/12 pole outboards." Can someone explain what that means. I thought any tach with a system check plug was a plug and play replacement for my oem tach--am I missing something here?
