Part number 91010123 This is a universal harness for the Ford muscle cars from 1966-76. It does have the headlight plug ins but will need to be wired to your original light sockets, switches, etc. It is 12 circuit and also has a 20 amp relay circuit to use with high current draw options. For a more direct fit we offer harness for the 64-66, 67-68, or 69-70 Mustang. Either of the mentioned harness will work with the Thunderbird cars. Several other painless harness are available through Speedway and we also offer American Autowire harness. Their kits comes more specific and include all the switches and light sockets. An example would be part number 91051005 for the 67-68 Mustang.
