do you have to remove the canister? Its hidden anyhow. There's a hose coming from it, that goes to your Canister purge valve solinoid, which should be dangling in the engine bay, near the firewall, close to your EGR.
You can remove the TAB/TAD solinoids, which are related to the smog pump, if your not running that. I dont see how they can work, or what purpose they serve once the cats are gone. Just unplug and pull that stuff out, along with the vacuum lines.
As far as hiding wiring goes.. theres not alot to it. I believe i had to lenghten the two headlight plugs with extra wire, about 6" or so. To tell you the truth, i cant remember exactly how i had my wiring, since i have changed it completely, and removed a bunch of extra plugs. If you would like to see pics of how its set up now, i can do that.
If not, i know Jesse ( yellow5.0cobra, i think?), on here, has done the wiring hiding. he might have my old pics, and the old thread, in this forum.
