Installation Notes and Quality

Verify connector shape, terminal gender, and vehicle position before installation. This socket does not include a wire pigtail, so the existing harness connection must match the vehicle application. Dorman designs this replacement socket to follow original fit and function requirements for the listed Ford, Lincoln, and Mercury vehicles.

Dorman 645-125 is a direct-fit electrical socket replacement for service work on turn signal circuits where the original socket no longer provides a secure or consistent connection.
