Default A grommet for a huge 1.5 inch square sensor

I need to pass my O2 sensor plug through the firewall. .. are there no grommets that are big enough for a 1.5 sq inch plug?

Check the grommet directly below the steering column in the drivers side footwell... you need to peel back the carpet slightly, should be large enough.

Absolutely do NOT cut/re-solder any wires having to do with 02 sensors. One thing you could try (that might sound a bit scary) is to get a peice of re-bar, and ream out the hole for the grommet until it is large enough, then use a flathead screwdriver and hammer from the other side to get the hole back to normal size.

you can CAREFULLY release the terminal locks, pull out the terminals and wires, and feed just the wires through any old grommet. Then simply reinstall the terminals/wires in the correct locations.

btw how about that big hole just below the driver side dash. there was a plastic covering there but when i peeked in it just seemed to go into the rain ducts below the glass... is there a way into the dash or car from there?

Ugg, i hate getting wires out of plug ends. But that seems like the best idea, if you dont have any other place to run it.

HOK - the simplest way to feed that WB02 sensor is on the passanger side tranny tunnel area just in front of the shifter assembly.... drill a hole in the tunnel area to pass the plug through. This spot will allow you to either plug it into either one of the O2 sensor bungs (before or after the cat).

Or you can try finding the moisture/water drain tube that goes from the inside of the cabin out through the firewall.

I think its an issue of adding resistance to the wire, this would cause a bit of delay, but i really dont think its that big of an issue.

Actually, it's because the sensor element needs an oxygen reference, I gets that by capilary action through the wire. Soldering the wires greatly slows down that action.

What kind of % or other measurement are we talking about? will it delay it by double?

I just don't to start messing with the firewall as things rust up here pretty quickly...

do you guys know what grommet I'm talking about that is by the windshield on the driver side?

I am not feeling the Capillary Action explanation. The signal gets sucked up the wire?

Where did you two learn about electronics???

Unless the wires are shielded (they may well be) or they have a specific impedance or something (that may be the case) there is no worry about soldering them.

Solding wires will not change the amount of time it takes for a signal to get through the wire. Soldering correctly will not add to the resistance of the wire. The oxygen reference for an O2 sensor comes from the back side of the sensor itself, not the wires.

All that said, I think your best bet is to pop out the wires directly at the connector as suggested above.

jesus christ
thats like my friend when he wired his neon lights backwards and had the switch set to ground out the circuit, i flip the switch and light up half his dash <by light i mean the wire caught on fire> i was like you idiot and hes like DUDE dont you know anyhting about electronics? the energy backfires up the wire and it fried itself thanks!

Well I have only taken one basic class for electronics, and the instructor was from another country, so I really didnt get anything out of that class. I was just curious on why you couldnt cut and solder the wire. Thanks for the explanation.

And White 2.5rs this is not wirering lights on your ghay friends cars.

O2 sensor wires are shielded. which is why they cannot be cut and resoldered. What's on the other end of the plug? would it be possible to run it the other way?

for that hole I believe that is just for access to the wiper assembly and you cannot get into the cabin from there. and if you did, your wires would be running next to the wiper assembly and most likely would get cut.


and yes, white2.5rs what did that have to do with anything, besides general electrical incompetency? it added nothing to this thread that's for sure.

Okay, I have another serious question.

So if the wide band ego is shielded, then it should not matter if its ran next to other wires that are for my TEC 3? Would it be best to keep it away from all my other wires? Do I need to wory about cross talk, or anything else?

here is the link to exactly what i'm talking about...

http://www.hokman.com/hok/images/car/hydraharness.JPG

I didn't post as IMG because its a repost... but what it shows is the O2 wires. The other end is already attached to the wiring harness of the 2.5 RS harness. I was thinking at the other end of the plug where the black shrink wrap is that I can resolder it there. doesn't seem shielded there.

I can take more photos if need be...

TIA
