Posting this as I wished this information was available when I did this install. Here is how I installed dual Zeitronix Zt-2 widebands. A post for a 3.5 Bar boost sensor I am integrating with this setup is forthcoming.

Not a difficult install, just takes patience. Here is a parts list:
-Two, Zeitronix Zt-2 widebands
-Two, O2 sensor bungs
-Anti-seize paste for installing O2 sensors.
-Electrical connectors (I went with crimp style weatherproof connectors that I shrunk with a heat gun)
-Sharp knife
-An add-a-circuit
-Wire crimpers/cutters
-Heat gun
-Adhesive for sealing the cuts you make in the grommets to feed wideband cables
-USB to serial cable adapter (driver for whatever adapter you use)
-Zeitronix software

1.) Widebands

2.) Remove liners in fender wells, cut grommets and feed wideband harnesses through. Dangling is the wideband and its harness, which were fed through an opening in the fender and dropped down to the exhaust between the body and motor. First, passenger side then drivers side.

3.) I installed the wideband controllers on the passenger side so, I fed the harness for the drivers side sensor under the dash over to the passenger side.

4.) Both harnesses for the sensors and both controllers in the passenger footwell

5.) Power: Since Ford appreciates you so much as a customer, they made the empty, number 5 fuse location located in the passenger side kick panel a 12V, ignition on source for power. Fortunately, Zeitronix builds 4 amp resettable fuses into their controllers so I ran both systems both off one circuit with a 10 amp fuse (I was only able to find a 7.5 amp or a 10 amp fuse.) I used 18 gauge wire to get power to the controllers and also to get them connected to a ground.

6.) Reference included instructions for wiring. In my case, I wired the boost sensor to the driver's side wideband controller and then the output from the passenger side controller to the input on the drivers side controller. This allowed me to hook my laptop up to just one wideband controller and read both AFRs and the boost sensor I installed. Once wired up, plug the respective AFR harnesses & signal connectors into the respective AFR controllers.

7.) The hard part. Bungs. There are four O2 sensors from the factory. Two downstream in the cats and two upstream in front of the cats. Some remove the downstream ones, put their wideband O2 sensors there and turn the downstream O2s off in the cars ECU. I elected to have bungs installed in front of the cats just for the wideband O2s.

The driver's side upstream O2 sensor is in the exhaust manifold. This is great as you have plenty of room to install the wideband O2 and a bung. On the passenger side, the factory upstream O2 is in the exhaust in front of the cat right before the manifold. This, combined with the starter being on the passenger side makes things very tight.

To install the drivers side wideband you probably want to drop the X pipe and cats (what I did) to drill a hole and weld a bung in. This isn't hard.

Someone may have been smarter than I and done this differently but here is my experience: To get a wideband on the passenger side, the exhaust shop I went to cut the X pipe off behind the cats, dropped the cats out of the car, installed the wideband in front of the upstream O2, bolted the cats onto the exhaust manifold and welded the X pipe back on. They did this because clearance is tight and you have to shift the entire X pipe and cats about two inches back to get them off the exhaust hangers. The added wideband would crash into the body of the car had we not cut the x pipe off and simply tried to reinstall the X pipe and cats as one piece. Here is the driver and passenger sides. On the passenger side, the wideband O2 is in front (not directly in front) of the factory upstream O2.

All of this headache could have been easily avoided if you are comfortable mounting your widebands on the bottom side of the exhaust pipe (6 o'clock for example); however, it is my understanding that doing this allows condensation to sit on the sensors leading to premature failure. The way I did the install allowed me to set the widebands how they should be, which per Zeitronix, is between 10 and 2 o'clock.

8.) Driver for serial connector to USB downloaded and installed, Zeitronix software installed, and wideband controllers powered up.

9.) Confirmed everything is working correctly, pulled slack out of wideband harnesses in the engine bay so that they aren't resting/going to get caught on anything, sealed up the grommets, reinstalled fender liners, cleaned up passenger side kick panel and permanently mounted the controllers on the inside of the firewall in the passenger footwell.

Done. Feel free to ask questions. Hope someone finds this helpful.

Excellent write up! Thanks for posting. I was looking into doing zietronix setup for some EGT and other sensors. But I'm going to integrate into my Ngauge to read.

Very nice! I have contemplated doing this on my 2008. What was the parts cost for the complete both side add?

...........................That 12V feed that you mentioned behind the passenger side kick panel?..............Hmmmm, maybe that is where the 12V comes from for the passenger power seat on the GT, that is not an option on the GT500 (the earlier cars).....

I admire your dedication and persistence towards installing a wideband O2 sensor on the passenger side stock x-pipe. You are the first I have seen in this forum attempt it. I did my homework as well for all possible pre-cat mounting positions with the correct sensor orientation, and I decided on a single sensor on the driver's side for easy serviceability. You are correct, there is very limited space on the passenger side, and I would offer that the passenger side is also more restrictive due to stock O2 sensor positioning and the reduced pipe diameter.

Here is a previous post for my install: Ngauge and electrical question

Ok, so that adds another question about one side or both sides? I am not an expert, but from what I understand, the readings for proper fuel/air are made between the MAF and the O2 sensors and any foreign air leaks between the MAF and O2's can be accurately detected by a wide band set up................So what if only one side is wide band installed and there is a leak, either intake to cyl head or exhaust (header/manifold flange, etc.) ahead of the O2 sensor on the other side?...........Can "that side only" run lean/or rich because of that air leak and an owner would never know because that one side is not set up with a wide band monitor?

I guess my question is.........Is a "one side only" install of a wide band monitor on a non-wide band car only realistically half monitoring the system?

Monitoring AFR in only one bank is better than not monitoring at all. You can also datalog short and long term fuel trims for both banks and compare values to see how your car is fueling.

Ok, and I understand one is better than none, but both would be optimal, two gauges, one for each bank so at a glance you know exactly what is happening on each independent side?

^^^^^^This would be for normal driving, no laptop laying on the passenger seat, nothing connected to the OBDII port.......just normal gauge monitoring.......

Yes, both would be optimal.

In reality, if you are confident in your Tuner, your mechanic (me in my case), and the quality of the parts installed on your street car, you only need to perform a thorough datalog and performance checkout once in a driving season. Once you know everything is still working well, get out and enjoy driving the car. I like being able to monitor critical systems, but I do not let it distract me from the drive.

I picked up this neat little calibration level AFR monitor on Black Friday, not for my GT500, but I am going to do some testing and make some tune adjustments on my dirt bikes in the Spring.

Can any wide band gauge choice be used with this OP set up or is it vendor specific to their gauge(s) only?

From personal experience with my own cars and some friends cars if you're only monitoring one side always choose the left or drivers side. That side has a tendency to run leaner or see detonation easier especially cylinders 7 and 8.

Quick question why not buy the zt-4 instead of 2 zt-2's?

I was thinking the same thing before I bought my Zeitronix wideband kit. I talked to Lund Racing before I bought it and they were fine with just a single 02 on the drivers side. Fast forward to months after my Lund remote tune session and the car runs great. Definitely pulls harder than the KB emissions tune. A/F ratios are spot on.

Generally speaking, in AFR kits the wideband O2 sensor and controller are a matched set for power and signal commonality. Exiting the controller, they will usually have a 0-5 VDC analog output. Any non-standard gauge that allows the user to input a conversion formula to convert the analog DC signal into AFR would work. For example, my AeroForce kit conversion formula is: (X volts times 2) + 10 = __ AFR. When datalogging AFR and Boost with my SCT X4, I connect the analog outputs from my wideband controller and MAP sensors to my X4, and it records raw DC voltages. In order to interpret them, I have to enter the correct conversion formula for each in the SCT LiveLink application so that the information is depicted graphically as AFR and Boost.

^^^^^^Cool, and thanks for the info. I am just trying to put together something for my 2008, I would like to be able to monitor for problems, my tune is the latest tune from KB, well, actually a couple of years old. I would like to mount two matching digital gauges (right bank - left bank) in a double pillar pod down low by the dash, out of the way, but visible at a glance and Black screen when they are off, so they are not noticed. I am just trying to put together a plan of attack to accomplish this.

So does the ZT-4 bring both signals into one box instead of each bank having it's own ZT-2 box? or how does that work?

Yes the zt-4 has one box. I had it in my car. I am selling mine now.
