wideband routing
I have a Innovate LC-1 wideband (not that it matters, just being specific), and I'm trying to decide how to route it. I have my other gauge wires routed through the hole down by the pedals and going under the fender, but I'm afraid the wires on the wideband won't be long enough or they'd be too bulky to run through there with all the other wires, so I was hoping to run it through the passenger side or under the tunnel or something. Anyone have any suggestions and/or pics of how you ran yours? I'd like to keep the "module" out of the engine bay if possible, but to do that I'd have to run it through the passenger side and there aren't any holes over there that aren't being used like there is on the driver's side.
Also, will it be a problem if I don't have an O2 sensor plugged in for the computer to read or will the wideband be good enough? Do I need to run 2 sensors is what I'm asking.

What kind of ecu do you have on the car? You can runs the wires through the passenger side. Right under the ABS system on the passenger side you will see how the main harness goes through a hole. You can slide the wires in through that hole.

I got a PFC for an ECU. I have a brand new harness so I had to pull the old one out through that hole, yeah I know what you're talking about. I thought about running it through there but I was afraid it would eventually wear on the wires and start cutting through them.

Here is an old writeup showing my install.
You should not be running the wideband sensor in the stock sensor location. cf. TechEdge's site for a detailed writeup on locating a wideband sensor.
The stock computer is definitely not going to be happy without a sensor, though your wideband may have a narrowband output that you can feed to it. If you have a PFC and Datalogit, you can simply turn off the stock sensor input.

That's really clean, thanks! So you ran yours through the driver's side? I can probably do that, but I'd rather keep most of the wires out of the engine bay. And I guess I'll just shut off the sensor input like you're saying. I like where you mounted your Datalogit too, I might have to steal that, haha.
You can run the wire along the brake booster line that spans most of the length of the rear of the engine bay.
I've since sold my TechEdge and am now installing a PLX SM-AFR and will probably route through the passenger side. However, unlike the driver side, I will probably have to trill an access hole in the fender area of the firewall. I don't want to screw with the stock wiring harness boot.

The link to my battery relocation writeup shows the driver wheelwell routing.

Ok, you can take out the stock narrowband o2 sensor and put the new wideband in it's place. Route the wires through where the main harness is on the passenger side. If you are worried about the wires getting worn/cut wrap the wires in electrical tape. You can disable the o2 sensor on the commander, and the ecu will run on the map it came with. If you had the ecu tuned, it will run off of that map.

I have the lc-1/xd-1, pfc and datalogit. Ran the lc-1 wires through the transmission shifter hole. Very clean, no problems. Also used the stock sensor location on my aftermarket downpipe. . .2 or 3 years now, no problems.

^yeah that's what I was worried about too. That tranny may not be as hot as the exhaust but it's still pretty freakin hot.
Do you remember who did the writeup? Thanks for the info!
After thinking about it, I think I'm gonna just run the wire along the back of the engine bay like moconnor did, that way it will be very easy to unhook the O2 sensor if I ever have to remove that or the DP. I'll just wrap the wire with thermal wrap or something to keep it cooler and hopefully keep water off of it if it rains.
Thanks for all the input and ideas guys.

One of the most important things is grounding everything properly. There's a good writeup somewhere in here on how to hook up this combination. It was very helpful. Also, remember to program your datalogit properly for for this setup. . .you need to go to to setup then auxiliary, check the box that says "delta AN1-AN2" then in the upper left hand box set 0 volts to 7.35 and 5 volts to 22.39.
