OK Boys & Girls, it's a 74' Explorer "The Blue One". Everything I can find says the 3 holes should be ignition, brake light, cigar lighter. Thats all good except the 3rd hole ain't big enough for a cigar lighter?? It also has a rolled bump around it. Went back and looked at early pics and it had been used but nothing there when I got it. Any help!!!;D;D;D
