I re powered my boat with a 2022 Yamaha 4 stroke F70. It had a 2002 TLRA 90 HP 2 stroke with 6Y5 tach, speed and fuel management gauges. I have bought a 6Y8T-21 tach and a 6Y80-20 speed/fuel gauges to put on it. The new tach came in a kit (6Y8-0E83R-81-00). The existing 6Y5 tach has 2- 4 pin harnesses that go from the engine to the tach in the console, It also has the 10 pin engine main harness. I need to know the harness part number for the new 6Y8 gauges from the engine to the console. I think I can figure it out from there. I also need a part number for the command link gauge installation manual, please help. Thanks, Tom
