I cannot find my diagnostic link. I have a 92 camaro RS 3.1v6, Haynes manual says it is right there under the driver side and I do not have a panel underneath the instrument cluster anyways so it should be sticking right out. I could not find it, took it to AutoZone to have them look for a trouble code so they could find the darn thing, but the guy wouldnt test for a light that isnt always on. He told me it was under the passenger side. My friend and I searched both sides throughly and found nothing. Two silver boxes on passenger side no diag links.

My car may have had v8 engine swap back with its original owner so maybe it was moved but how can I find it now??
