Mods made by P.O. What do I have with this engine bay harness?

Next a couple pics of other cars from Carlisle. I believe these were both 74. The red one shows the regulator where mine is and also one of the magic emissions boxes on the firewall. I think this one is an EGR dalay timer IIRC. The brown car shows what I believe is a start cutout on the inner fender behind the washer bucket. You would have had this with your seatbelt interlock. I don't have a good pic from the other side of his bay, but I believe his regulator is in a different location. This car belongs to a FABO member, Booker? I think?
