I went to have my oil changed in my 83 300D and the vacuum hoses are near the oil filter the Techie dislodged several of my hoses and the car will not shut off with the key. I found two out of the threeconnections for the hoses, however there is one small diameter black hoses that goes through the fire wall under the dash that I cannot find the connection. Is there any hope. Thanks

 

Thanks ForcedInduction for that info. Even thought I have the other hoses hooked up it still will not turn off with the key. Any suggestions?????
