I should’ve done a better job at taking pictures before staring in this. Boat is a 2009 Yamaha 212ss with twin mr1 ho motors. I have two relays that I’m not sure are hot or negative. Cable connectors are black which make me think they are negative but the relays are red. Anyone have a electrical diagram for these motors?

I don't know if this helps, but taken from my 07 AR230 HO service manual. Same engines.
