I'm putting a 1986 merc 150 on my 1994 Trophy 1802. It had a Mariner 150 on it. The problem is that the Merc has a 12 pin connector and the boat has an 8 pin connector. Is there an adapter that I can get or do I need to buy a 12 pin connector and wire it to match the engine? <br /><br />Where can I find wiring diagrams of each?<br /><br />Thanks,<br />Kevin
