I need a quick answer... November 01, 2014, 06:29:51 PM On an '88 Thunderbird, there should be two plugs for the OBD 1 testing. The big plug is easy, what color is the single wire? Quote Selected

I need a quick answer... Reply #6 – November 02, 2014, 06:25:27 PM My gray plastic piece is missing, but, I can locate that gray piece and snap my wire into it. I have a holder for those plugs to snap into when not in use. I think I'll install that next weekend. Just have to drill a small hole and it snaps right in. Then the plugs into it. Quote Selected
