Vacuum lines to/from Evap switch on 1997 GTP

I was getting a P0304 Code (Misfire #4) so I removed the sparkplug wire from #4 to check it and the plug. In the process, DUMB*** me knocked one of the vacuum lines off the evap switch. I have searched and can't find it and none of the vac line diagrams that I have been able to pull up show 3 line on the evap switch (only 2). Can anybody give me a diagram with 3 vac lines on the evap switch or tell me where the ines go from the switch? Thanks
 


I wish it was that easy! As I said in the post, I knocked it off and now I can't find it. If I could just plug it back in I wouldn't be asking for a diagram.
 


mine had a white pinch clip on the end, you see it to the left of the red tranny dip stick. mt evap is deleted so its just hanging out back there.

I checked that area again and still no luck. The lines that are still connected go to the evap canister purge valve and to the evap canister. Any idea where the third one is supposed to go?
 


This is my evap switch. As you can see there are2 hoses attached yo it and one open fitting. That's the one I can't find.

Don't know why but the photo came across upside down. The nipple is actually on the bottom of the swich pointing down towards the valve cover
 


As soon as I fire it up, it pops a P0171 code now. Having read more than one post about that code I know I've got a vacuum leak that I didn't have before I knocked the hose off.
 
Where does the tee'd hose that runs under the battery and then back towards the firewall go? I know that the other side of the tee goes to a vacuum bulb in the driver side fender but I can't trace the other part of the tee. I'm wondering if that's the one that I knocked off and should be supplying vacuum to the evap switch. I'm just asking because I don't have a clue
