I have just placed AutoMeter's diagrams for installing the A/F gauge up on the web to try and give some understanding what I am trying to say in regards to where the gauge wire must connect to the sensor.

The trouble is reaching the sensor wire after the connector to splice the gauge wire into. Is there another location that can be reached???

That was funny.

But to answer your question, No. I helped put the FAQ's together and I don't recall anything about tapping into the sensor wires going into them.

That would have been reeeeally embarrassing of it was there.

So far, I have been to a number of auto mechanics, service stations, etc. and no one wants to locate and splice the wire into the 02 sensor connector. A few of the mechanics said that they could not do it because it would be considered altering the emissions and one said that it would be against the law.

O well, on with the quest. And while I'm questing, if any of you auto-geniuses got an idea, I would love to hear it.

hi,

i connected mine right undereath the manifold.. there is a grommet in the firewall almost right behind the brake, and i ran i wire through there and down to the sensor and connect to the black wire. it's not hard, just make sure you tie the wire to something so it doesnt touch the manifold and melt.. i would take a picture for you, but it started to snow today, and i'm not too fond of laying outside. if you absolutely
cant find it, i'll take a pic for you sometime next week when i have some days off. hope this helps...

I can see the 02 sensor on the manifold but where AutoMeter says to connect to is about six inches above the manifold and it is in a position that I am not able to reach to splice into.

Did you connect to a wire that comes directly off the sensor on the manifold and not from the computer side of the connector??

Question HELP! Has anyone connected an A/F gauge to the L's??

HELP!

I know where the sensor is on the manifold and from underneath the L, I can see the sensor wires coming off manifold and about 6 inches from there they connect to the computer side of the connector.

It is the computer side that we are to connect the gauge wire. But I CANNOT get to it from under the L and I cannot locate where the computer side of the sensor wire runs to after the connection. I know it runs to the computer by way of the harness but I don't want to disturb the wires at the computer. There too many wires at the computer.

Has anyone connected the A/F gauge and if so, where the heck did you plug into.

I read where someone connected to the 02 sensor side of the connector but all the instructions both in the gauge package and on AutoMeter's web site says to ONLY connect to the computer side of the connector, not the 02 sensor side because of the type of wiring used on that side.

HELP!

Anyone have any ideas?

Hey Jim - Do you know anybody that does network or phone wiring? The reason being is those guys usually have a toner that you can use to track down a specific wire out of a bundle of wires. I'm going to see about borrowing one from the Telcom guys at work and see if I can track this sensor wire back to a place that is easier to get to. I’ll let you know what I find out.

By the way, I noticed your last post on this was at 2:31AM???? (could be that post times are EDT which would only be 11:31PM your time) Get some sleep man or you'll be too tired to drive once you get this figured out.

Hwy

It was about 11:30 when I finally went to bed. My wife and I went to a going away party for a relative that is going into the Marines next week.

I'll be watching for your post to find out what kind of results you had.

Jim - Check this out

Using info from this thread:

Hello everyone. I made a mistake in saying passenger side. It should be the driver side o2 sensor right below the collector on the header. The black wire is before the harness from the o2 sensor ends. After that it turns into a red wire with a black stripe. You can wire it up by the pcm but it is too difficult to find the wire there. I carefully stripped the insulated black wire back and ran the autometer wire piggyback off of it. For the power, you can hook the wire to any control in the fuse box which turns on with the ignition switch. I would hook it into the transmision control fuse or Rap module fuse.
With the key part being
The black wire is before the harness from the o2 sensor ends. After that it turns into a red wire with a black stripe.
I got a Ford wiring diagram from the ToyMan that shows the red/black wire mentioned above running back to pin 87 on the PCM.

I haven't figured out a way to post the diagram but I will email the info I got from ToyMan to you. Have a look and let me know what you think. We will also need to figure out which one of the pins is #87 at the PCM.

Rick

Update - Here is the diagram

Lower right hand side is where to look

Sorry about some of the pic quality. Hey you work with what you have.

Thanks for looking these up in your book ToyMan.

O2 Sensor Side of
connector.
DO NOT TAP INTO
This is a quote from AutoMeter. This is what I was concerned about. The black wire is on the sensor side of the connector. I realize that the black wire connected to the red/black wire would be virtually the same but why does AutoMeter seem so dead set against tapping on to the 02 sensor side?????

Probably because if you have to replace the sensor you will have to cut and resolder the gauge wire. It also forces you to connect to the wiring harness away from the hot exhaust where you could melt the wire.

Jim,
Slick X has it right. It's black on the sensor side of the connection and red/black on the harness side. Where he did it is fine, other than you might have to redo the connection if you have to replace the sensor (I agree with Mark_2kL post above). If you want to do it like Autometer says you will need to find the red/black that connects to the black on the sensor.

Hey Jim - Are you going to put all this in the FAQ section? You can have the diagram pics. They are posted on my zing account.
