What is the box on in my 997S trunk?

[bencomer]

I am installing a Dension Gateway 500 and a BTA 1500 in my 997 S Cabriolet. I am trying to find the best way to route the BTA

Is the black box next to where the CD changer used to be? That looks like a Black Pelican Case? if so, it's the carbon canister. That box is connected from the bottom to the gas tank's lines.

Here is a picture of the box I am referring to. Yes, Joel, it is near where the CD changer would be (if I had one). What is the purpose of this box? Before realizing that it does not easily pull out, I cut a small hole in the rubber grommet behind it, thinking that it connects the battery compartment to the trunk, with the idea that I would pass the BTA-1500 wire through this soft grommet easier than any other place. Once I cut the hole, I realized that the grommet leads to the back side of this carbon box. Once I realized that the box does not lift out after loosing the torx screws, I got nervous that I have sliced a grommet that needs an air-tight seal.

I have two questions. Does the grommet connect to the back side of the box? If so, have I damaged it by cuting a small slice in the grommet? If the grommet does not connect to the back side of the box, how do I lift the box up enough to pull the BTA-1500 wire through the hole I cut to pull the wire into the trunk?

Thanks for your help.

yes, that's the carbon canister.... try not to mess with it since the unit needs to be airtight for venting fuel gases... so, unless you drill a hole to this box, I think you are going to be ok... I had a similar install than yours... no cd changer and put the dension and iPod on the trunk. everything works great!

OK, thanks Joel. If your install is similar, how did you route your BTA 1500 cable from the battery compartment to the trunk? Did you find an existing grommet to go through, or did you have to drill a hole through the wall?

[Joel Pirela]

I didn't.... I got the constant power from the wire connector to the cd changer preparation tat you have on the left of the carbon canister. is a little plug that is hanging loose. you just tap to that and you are done...

Did anybody ever figure out how to use the grommet behind the carbon canister?
