The instructions are all in Japanese. There is a wire harness and I want to be sure of what each color wire does.

The colors are:
Red
Black
Orange
White
And a Yellow wire with a connector

Thanks for your help!

 

Okay, I will try to help you, but I have Defi gauges... Might be different colors. Yellow should be for your egt probe. Black is ground - anywhere on the chassis. White is illumination - tap the dimmer switch. (I'm doing this all through my head so forgive me if i'm not being specific enough) Red and Orange are your constant 12v and ignition on 12v. Not sure which is which. You can probably find that out though. Get a add a circuit and connect to in cabin fuse panel empty slot #10 for constant 12v and 17 for switched ignition 12v.

 

This is the way somebody told me to do it. Oh and good luck trying to get someone else to help you... 1 person responded to me.
