Hello I am installing a new Yamaha 175 hpdi on my boat and need a little help. I have a side mount control setup and the wire colors do not match what I am use to. Mercury and OMC use purple for power, grey for tach and black for ground. The yamaha colors appear to yellow for power, green for tach and black for ground. This is my first yamaha to install, but have setup several mercuries and omc's. Thanks in advance.
