Wide band O2 location

[J5races]

Hello all, new member but been lurking for a while now. I’m adding a Whipple Gen V kit to my 2018 Tahoe RST when it arrives.

I bought an Innovative PSB-1 AFR and boost gauge. I have a few questions:
1) where should I have a bung installed for most accurate AFR? I realize I’ll only be looking at one bank of cyl
2)Where should I get my boost reference for the gauge?
3)Which wires do I tap into by the driver foot area to get the lights/switched power/etc for this gauge? I’m good with wiring just need to know what wires are what I need. I’m extremely handy with a soldering iron. But don’t know the Pino it’s of the Tahoe

Thanks all!

Only 1 WB sensor you want to be shortly after the y merge so you get both banks on the reading. Typically the sensor MFR will give instructions on where they want it located.

Should be an unused port on the back of the manifold you can use for the boost ref.

I have the same sensor but have not installed it yet. Instructions on page 7 states before the catalytic converter and between 9:00 and 3:00 o'clock. Preferably at 12:00.
Goat rope garage has a decent video of where he put his wide band.
Whipple should have a plug port on the aft side for using as a boost/vacuum reference point for your gauge.

But that would be after the primary cats right. Isn’t that bad because cats change the oxygen reading?

I don’t have the parts yet. All on order. Been saving up for the whipple for a while now.

Anyone know about the wiring?

This looks like a good spot.

Dash Cam wiring for 2019 Tahoe

Where can I/should I connect the power wire for a dash cam? I want it powered only when the ignition is on and not powered with retained accessory power (RAP) or when the ignition is off. I have a hardwire 12v-5v accessory cable, an add-a-circuit mini-fuse tap, a usb cable and a cigarette...

Also found this for wiring to make the gauge work at night.

And Power Distribution wiring diagrams.

And the rest.....

Do you have long tubes?

Do you still have secondary cats? If so, just put it in the secondary cat.

Are you wanting the wideband permanently mounted inside the cab? If so run the wires through the firewall.

I just plug mine in and hook my laptop up when I want to data log (cord ran through the window and painters tape holding it along the door so it’s not flapping in the wind) and then unplug it all when I’m done. Power for my AEM wideband is supplied through the 12v cigarette lighter.
Don’t need a permanent AFR gauge hooked up personally.
