I have a 2000 Honda Accord with an F20B. I'm trying to wire my Air Fuel Ratio Gauge, but it seems that my wiring is different from all the others.

On my harness, the O2 sensor has 4 wires: Green and Black, Black and White, Black and Yellow, And a black wire that is a slightly lower gauge than the other 3 wires.

All of the diagrams and forums I have read say nothing about any of those wires. 2 of those wires make the gauge go all the way up, and the other 2 make it do nothing.

I have read about tapping into the wire from the ecu, which is the white wire on pin c16. This wire just makes the gauge read at lean and it doesn't move much.

Any ideas?

 

Who makes the gauge? Might want to check their website.

 

It's a Glowshift Gauge. I hadn't bothered to check their website, I'll do that and reply if I find anything.

 

Yeah. That's not a real AF gauge.

 

That's a light show gauge not an AF gauge. Don't waste your time as it won't be accurate or helpful at all.
