Vacuum lines and wiring
Does anybody have some good pics of their engine compartment? I have a 84 Regal with the 3.8 and AC. My smog pump is missing and the wiring is a disaster. I know there are schematics out there but my brain doesn’t work that way. Any help would be appreciated.- Street Sweeper22
