Hey-
Just re-doing the exhaust on my 87MJ and put on a Clifford header. Vacuum lines were screwed up to begin with, and then I got started. I know from the TBI, vacuum is to the MAP and the valve cover. I know EGR solenoid vac line goes to EGR, and manifold vacuum to HVAC. Theres a second manifold vacuum source I'm not sure where it goes, and there are two ports on the air cleaner housing, one is functional and one is just a plug. What goes there? If anyone has been through this headache, please share some information!
Thanks in advance
