If you get some useful info on this let me know I too would like to know where to find stock connectors

Just wanted to point out a really stupid error I made in hopes it saves someone else during the install. It didn't make any sense when I was doing it, and this caused me to double check the wiring diagrams, and low and behold, my haste led to an error. In regards to connecting the AEM Failsafe wideband, the white wire that you tap into for the analog AFR data is not the white wire coming off of the Uego wideband, but the whitewire that comes out of the AEM gauge cluster. This is logically obvious, and obvious if one spends 5 seconds to look at the AEM instruction manual. You will find this wire, along with the brown wire that needs to connected to ground for the analog output. Simple mistake, but no point in two people making it.

I ended up finding one, but i'm not sure which part # i ordered. It was either the subaru or toyota one. I wish I could tell you which one worked because I ordered them both and had them separated so i could keep track of which was which, but my girlfriend managed to do some spring cleaning.

I'm almost certain the Toyota one was the one that fit: http://www.casperselectronics.com/st...oducts_id=1306

but here's the subaru one just in case: http://www.casperselectronics.com/st...oducts_id=1395

Hey @sportguy83

Do you use the whole length of the signal wire of the AEM gauge or you connect a new wire from o2 into the cabin and then fuse to the gauge output wire, meaning the AEM output wire is as short as possible? I'm thinking might be some resistance Issue because the AEM wire looks very thin!

I used the full length of the AEM wire and it made it exactly to the place I wanted cutting the Rear O2 cable fairly close to the sensor.

Thanks! I ordered the Toyota one and it fit just fine. Very clean install.

Sorry to revive this thread. I have my AEM wideband connected to evap. I can see the data in ecutek. I'm using a power ground which makes my AFR off by a factor of 1. Meaning in ecutek it shows 15.5 but the gauge would be 14.5.

What are you guys using for analog ground? Can someone please provide a pin and connector I can look up in the wiring diagram?

Installed my LC-2 on the rear O2 port today.

At first I tried using the power and ground ports on the plug to power the whole thing. However, it seems it shares a ground with the throttle body. When I powered it up, as soon as the O2 heater turned on, the throttle body freaked out.

The LC-2 must be pumping a ton of noise across it's ground. I ended up running dedicated power and ground for it, and it seems fine now.

Just something to be aware of. Other wideband setups may be fine, I dunno.

would love to see some pics.

Question to the gurus out there @Sportsguy83 and @jamesm

If you use the cpc for flex fuel, can you still use it for the failsafe?

Are there any conflict issues?

Why not use the rear o2 sensor for WB?

[FRS_FIEND]

FML lol Do i really want to do my first turbo install on my own!

Its seems simple but then at times just doesnt! your first post was like a 2nd language for me! lol


I get frustrasted with stuff quick so i can see me punching my frs during this process! lmao

EDIT: MECHANICAL STUFF exhaust manifold DOWNPIPE turbo oil lines fuel pumps piping intercooler drilling oil cooler etc. CAKE!! "I got this"

ELECTRICAL STUFF: "FML I suck"

There are two Ecu inputs that ecutek can utilize. The cpc and the rear o2. You cannot wire two devices to the same input.
