Where is the power steering fluid reservoir for the 1986 dodge Aries?

It is located on the passenger side of the vehicle, right behind the "air box" or "air cleaner".....it should have a red metallic looking cap on it....that states to use only "specified fluid" - interesting enough, I found this page while searching for the "specified fluid" for my 88 Dodge Aries.....many sources seem to be telling me to use Mopar ATF+4 (which has replaced ATF, ATF+2, and ATF+3....), and to NOT use anything labeled "Power Steering Fluid" on the parts store shelves......

BUT the funny thing is, my manual even says to NOT use ATF :X hahaha....I think as long as I flush all the old "whatever" fluid is in there now....out....I will be golden.....good for another 18+ years.
