Where under the hood are the likely places for an OBD 1 DIAGNOSTIC TOOL to be connected?

What is your question?

1995 Lincoln Town Car. No start, cranks but won't start. Started a few months ago not starting about every 3rd time, gradually increasing til it won't start at all. Starter, alternate, and battery and cables have been checked and replaced if needed. Was wondering if could possibly have something to do with antitheft. Tried hooking OBD2 UNDER DASH BUT KEPT SAYING ERROR. NOW I CANT FIND THE OBD1 hookup.

What makes this problem better or worse?

Doesn't matter

How long has your 1995 Lincoln Town Car had this problem?
