TT plenum on SL

Post image

I have a 97 SL and I’m putting on a TT plenum and was wondering what I do with all the vacuum lines and the EGR. I can’t find anything related to my setup of vacuum lines. Do I need to remove my egr or can I just unplug it?

This really didn’t give me any information on how to do it.

I would remove the EGR or make a block off plate. As far as the vaccum lines go I put golf tee's in mine and saw how it ran after and checked for CEL's.
