Carbon canister to Intake where does it connect
 

I have an 86 300zx NA and I'm trying to figure out exactly where the line from the carbon canister connects to the intake. The line I am talking about is the one which leave the carbon canister and runs right along the rail at the front of the engine bay and then turns and runs under the unit mounted there, can't remeber if thats the alternator of the ac .

My vacuum line from the canister just stops there and I can't figure out where the actual connection is supposed to go. Thanks in advance!
