Plenum removal points for Gen2 V6 Camry
Hey man, I do not know if this will help you, but I have taken my plenum off like 3 times now and after the first time I labeled all the connections so I can print 'em out and cross 'em off as I put it back on (also color-coded the connections with multi-colored electrical tape and a Sharpie but that will not help you). We have a 1990 Gen2 V6 Camry (automatic) and the things I have to disconnect to take it off for back plugs/valve cover/PCV valve are:
