My LCD screen project, boost, WBO2, Knock, etc

Great job!

Today I am FINALLY installing this thing after having it since the tail end of last year. Everything has gone smooth but I have a few questions.

1. Orange or green wire is for WBO2, or does it matter? I know it is the WBO2/Aux harness, just don't know if it matters which one it goes to. I have a Prosport WBO2 with an analog output harness with three wires; black, blue (? colorblind), and brown. I seem to recall the brown wire being the one that I need, but I can't find my gauge instructions and Prosport's website (http://prosportgauges.com/Wideband analog instructions.pdf) doesn't mention it. 1.5: Does anyone know if it is the brown wire?

2. The aux wire; can it be used for an oil pressure gauge?

The stock sender should be accurate enough, it's the stock gauge that is inaccurate, correct?

The wire color for the WBO2 and Aux differ from batch to batch so I can't tell you which color it is, however the wire closest to the LCD display connector is the WBO2.

Best to contact Prosport, and ask which wire is the Analog 0-5V signal. You're also going to need to know what that voltage represents too. ie. 0V=10 AFR, 5V=20 AFR.

The only acceptable signal that goes to Aux is ground signal. It is meant to be hooked up to a switch, with one wire going to ground, and the other wire to the Aux. So when the switch is activated it provides a ground signal. So hooking up anything else to it would be an incorrect thing to do, so no to hooking up an oil sensor to it.

Some users wanted to hack their LCDBC into giving more information, such as oil pressure sensor. This involves soldering 3 wires, ground, +5v, and signal. So that's why you see those options in software, to support those hacks.

There's nothing wrong the stock oil gauge itself, it lacks sensitivity and numbers. Our oil sending unit sometimes get compromised over time, ie, bad electrical contact and then displays this incorrect data to the stock gauge.

Wow that install looks perfect lol

Thanks Antero, That's good enough for me. The PDF I linked has the afr/voltage scale on it so I'm all set there.

Mine doesn't look as nice as J2K4's, I couldn't get it up as high since I didn't want to cut the plastic light piece thing. I used it instead to keep the screen level.

I'm willing to share the identity of the fellow who hacked up my dash cluster...

Don't do it lol

If it's who i think it is, you shouldn't trust him. He's kinda shady

You can't trust those long haired types...

Yep, Sorry, I failed to RTFM. Actually, I was reading rather than looking at the picture. I got it all in and installed my chrome ECU at the same time. Worked first time, I couldn't believe it. I still haven't driven the car yet as I am currently in the middle of other projects on it too.

Thanks for your help!
