Default Need Instructions for an Air Fuel Ratio meter

I found in a box my Huntley Racing ARM1 I never hooked up. Does any one know where I might find hook up directions for this thing?

I've got step-by-step instructions along with photos on my RacerX website.

Rather than the involved step of extracting the pin out of the DME connector, you can just use some wire-strippers and push aside 1 /8" section of insulation from the inner wire of the O2-sensor cable after it's been separated from its insulation. Then wrap your signal-wire around it and solder. Wrap-up with electrical tape and reassemble the connector and you're set to go.

You might want to also put the ground wire DIRECTLY on the negative terminal of the battery.

There used to be issues with sensitivity if this wasn't done.

HTH!

SO
If I have this right the red , white and black are the lighting wires and the brown is the signal wire off of the O2 sensor and the orange is the ground for the sensor?
