Hi, I removed the intake manifold on my 1990 E30 to clean it, and disconnected all the hoses
and wires, connectors, etc. I reconnected everything but this one hose, that starts on the charcoal canister, and runs
upward toward the throttle body.
I can't find a place to connect it. See the photo. Can anyone help?
Thanks, Ray Lynch

Thanks viewers, I removed the throttle body, and was able to see a brass fitting on the bottom side of
the base. Attached the hose, buttoned up everything. Now it's running great, smooth idle, lots more power.
