hi its me again . sry about all the ?'s thought i'd ask before doin something stupid. I was further tracing vaccum lines that went to a vaccum tree. Had letters on it for B/B, A/C, S/c and one other. I gather B/B brake booster. My question has anyone ever removed this and just plumbed in the B/B? What does the S/C go to or do ?

Also on a totally unrated topic, Finished doing a battery location just one question on the ECM ground wire. does it have to be grounded right at the battery? Or can i ground it to a good bare metal spot? I have got mixed opinions about this so might as well ask the pro's Sry again for all the ? s

I'd leave ecm grounds in stock location and make sure battery to frame and engine to chasis grounds are all installed in place
