1991 c4 base diagnostic hookup
I just purchased a 1991 c4 yesterday and I want to have a diagnostic ran on it. Can someone help me to locate the port? All of the info I've read in regards to this have stated that it under the steering column in the right, but that has been for 1992 and newer. Thanks for the help

I have seen them shoved above the lower cover when the mounting tabs have broken. Try taking the cover off and looking around for it to be tucked up there.
