Has anyone had luck passing anything through the passenger side? I am trying to pass a small vacuum hose and don't feel like drilling through the firewall. I found a small wire with a huge groment from the engine bay. I passed a wire hanger through but cannot find it inside the car I don't feel like going all the way around the driver side ... any suggestions?

there is a hole about dead center in the firewall there might be a plug in but it goes straight thru otherwise anything u put thru the passenger side your going to have to take out the glove box and go fishing lol good luck

I had to go look at my car to see the spot you are talking about. I'm sure that the heat ducts are right behind that. But I saw another possible entry that is easier to get to. It's a black plug about 5 inches above the fuel filter and towards the center of the car. On my car, it's just a plug - nothing going through it.

Damn... you think like me but beat me to it. Good show.

Well I'm trying to get it to my glove box. I'll try the middle of the firewall tomorrow. Thanks guys.

Keep us posted on where you decide to route it. Im trying to route my wideband but cant find a spot.....

Damn, I completely forgot about this. I was working on taking my coilovers off to try and adjust them since they are seized.

As far as wideband is concerned, I had the car up on a lift today ... Idk where is the best place to install the bung? Maybe on the cat right after the flange. I don't want to do it the y-pipe just in case I decide to go with another one later on. I guess we can pass the wire up with the 02 sensor behind the cat? That comes up under the carpet i think under the driver side seat...

Optimum spot for an o2 bung is right after the fork of the y pipe before the flange. Wouldnt know where else to weld it other than on the test pipe (if you had one). You wouldnt get good readings downstream the cat.

As for snaking the wire through, if you do finbd a spot, take pics if you can. Curious about that spot under the carpet you mentioned
