Depends on the Century I guess... on my very old boat the purple wire is for the gauge lights... red and black should be hot & ground... I would imagine the blue is the sender, but it's hard to tell... I spoke with A&A marine in michigan and they were able to send me the schema for the entire boat, which ended up being mostly correct... correct enough to figure out the rest...

Re: I need diagram for gauges

In any case, you should be able to trace it out pretty easily... the hot wire will come off one of the ignition posts... the gauges' lights should come off the back of whatere switch turns them on... the ground is likely to be black... the other wire is the sender... Even if the ground isnt black, the lights get their ground of the gauge housing... so pull one of the wires off that you suspect my be the ground... if the light stops working you have found the ground... the other is the sender...
