I have an 01' SLK with the 3.2 V6, and I am needing to know where a couple of vacuum line goes to. If someone has a schematic of the vacuum lines on the firewall side of the intake it would be greatly appreciated. I am mainly trying to figure out where the vac line off of the top side of the EGR module goes?? There are also 2 steel nipples that are on the rear of the Intake (firewall side) that I need information on these also. Thanks!
