Wiring help

Thanks for all the info. I will be posting photos before and after

 

Welcome to the forum.

Most of these sort of things (dash and ignition switch) wiring are pretty basic, for an electrician or reasonably experienced handy guy, particularly the gauges. There are a few books on basic 12 VDC wiring, though if you're like many and just scratch your head with this sort of thing, you'd be best advised to call an electrician. It's nothing to be ashamed of, most are baffled by electrical stuff. It's not really that tough, but it does take some understanding to get your head around it at first.

 

PAR is right. If you want to start from scratch and do it yourself, it isn't all that mysterious. It just requires learning basic DC circuits which are simple. Start here. 14 steps to wiring your boat. http://newboatbuilders.com/pages/electricity13.html

PS: I realize that this page applies to outboards, but the principles are the same. You can sort out the wiring for the engine fairly easy because most of the manuals for the engines are available on line.
