Wide Band AFR questions

[sam69]

Where's the best place to pick up a 12v ignition on switched power supply for an Innovate wide band ...

Even did a google on this and didn't come up with much at all.

I have an LC-2 under my drivers side electronics along with my hardwired radar and whatnot. There's plenty of switched power sources for you to add in an add-a-fuse. There are even a few empty fuse blocks with no fuses that are actually switched. Grab a multimeter and test them out. Some are always on, some are ACC, some aer IGN. I can take a picture when I'm out at my car tomorrow.

Sorry I'm still somewhat lost on how to physically connect my AEM wideband sensor and gauge. Please be patient because I'm really dumb when it comes to wiring up electronics

I've got the AEM Digital UEGO AFR gauge (non-failsafe), and I'll be installing it in place of the factory rear 02 sensor.

But what I'd like to know is, how do I wire it up?
a) snip the stock sensor wires from the connector
b) fit the AEM sensor into the factory rear 02 bung
c) connect power and ground wires
d) join the AEM's 0-5v analog output wire to the blue wire off the factory connector

Is that correct? And will that allow my tuner to tune (using ecutek) accordingly? I don't have an electronic boost controller.

A pic would be good if you can and will have a go with the multi meter asap and see what I can find

This is a question best asked of your tuner. There are only so many wires or methods or getting an aftermarket signal into the ECU. It sounds like you have the basic idea though. I wouldn't cut the entire connector off. Go up stream of it a little and just cut the signal wire. You can get power and ground from inside the car.

My plan was to get rid of the stock sensor, but leave the stock connector in place and simply join the AEM 0-5V wire to it. So effectively replacing/swapping just the stock sensor for the AEM sensor....if that makes sense?

I suppose I could get to the sensor's signal wire from inside, if I had was leaving the stock sensor in place and fitting the AEM sensor on a 3rd bung....but in order to physically remove the stock sensor to utilise that existing rear bung, I'd still need to snip something off at that point, no?

Yes, you get rid of the stock O2 sensor and it's wiring/connector and tap into the wire on the engine harness side of the connector.

Ah okay I see what you mean. So when looking into the engine bay, there won't be any anything plugged into where the rear O2 connector would normally go.....yes?

Yes. The plug is near the cam sensors on the passenger side of the motor if I remember correctly. Just un plug the rear O2 sensor and then remove it from your exhaust completely. Then tap into the wiring side of the other connector on your engine harness.

Ok I'm planning on buying a wideband O2 sensor to replace my existing second O2 sensor. I'm doing this so my tuner can tune an AFR failsafe into my tune. Is this the type of O2 sensor I should be buying to replace my existing sensor?

That is just a replacement sensor for the Innovate LM2. This is what you need at a minimum:
