I am rigging a 1992 motor with a new style (multiplug harness) and adapter harness (big round red at motor to multiplug). I would like to run the system check gauges, specifically the tach with the idiot lights. What else is required to run this and/or will it work with an older engine? Also, I have a pair of omc oil tanks that were in my boat that I'd like to use one of. There is a single dual conductor wire with no connector, where would this connect, at the engine or control box?<br /><br />Thanks
