Please explain more about what it is that you want to do.

Does the tachometer (with the cut wires) not have a trim bar scale on the front of it? And, does it not have lights or LCD bars to provide status of the oil system?

The tachometer appears to be a later updated version, as evidence by the square nylon connector. The other two are older stuff based on their having round nylon connectors.

Let's start with the easy stuff first.

The tachometer has four single wires coming from it, each with a bullet connector on the end. Yellow is for key on power, black is for ground, blue is for the internal light and green is for the tachometer signal. These four wires typically attach to a small harness that runs from the 703 control box. See illustration below.

thats is easy. but then start the problem. Only few wire, that could not go wrong....

You are gonna need a trim/oil harness that runs from the motor to the tachometer and you will need to adapter harnesses to connect harnesses on the motor to the trim/oil harness.

Here is a diagram that shows what I am referring to. The parts needed are shown in the links below.

Double check your motor and make sure that it is configured as shown in the illustration. More to follow on wire colours.
