I'm in the process of installing a Yamaha MR-1 engine in a 16 foot DuraCraft. I have everything done, except for the wiring.

When this engine was pulled from a Yamaha jetboat, they failed to also remove the wiring harness that goes to the dash.

So, what I have is the engine and CDI, but there are 3 plugs that come from the CDI, and I'm trying to figure out what each wire is supposed to go to.

I have 3 different manuals, and none of them show this particular wiring harness. ??

Anyhow, here are some pictures for visual reference:

3 plugs with wires:

2 and 3 pin plugs:

10 pin plug:

Basically, I want to know which wires go to the start, stop, and kill switches. Also, which wires go to the tachometer, and which wires are the sensor wires for oil pressure, engine temp, etc?

I already have a wiring harness hooked into my console from where I had another PWC engine in the boat. I know where each one of those wires goes, but I need to know which ones on the MR-1 harness correspond with these.

Any help would be greatly appreciated!
