1997 mercedes e320 heater
 

I have a 1997 E320 that someone has disconnected the heater return line because it broke off. Does anyone out there have a 1996 or 1997 e320 that they could send me a picture of the hose hookup on the drivers side going through the fire wall so that I can figure out my heater problem? I am going to order a repair manual but Info would help get me on the right track. Also would yall recommmend me getting a Bently repair manual? Thanks
