I was wondering if anyone isable to provide a guide or diagram of wiring from gauges to computer then motor in my boat. A lot of Purple, black and red and Yellow( which is ignition and remote or memory). I have an hour meter, ignition, tachometer, speed, oil pressure and voltage. The loom looks standard so thought someone in that big wide world might be able to help please. Desperate to go fishing.
