so i bought a new a/c drier for my 91 (r12 system) ...im keeping the r12 system not converting...anywho i went to swap out the drier and the plug up top on the drier isn't there on the new one...very new to working with a/c system but what do i do about that sub harness that was on my original drier but nowhere to plug in on my new drier (my new drier looks like this as opposed to the one here with the plug up top)
