How do you install front and rear turn signal housings on a 1973 super beetle?

To install front and rear turn signal housings on a 1973 Super Beetle, start by removing the existing housings. For the front, unscrew the retaining screws and disconnect the wiring harness. For the rear, similarly remove the screws and disconnect the wiring. Once the old housings are removed, connect the new turn signal housings to the wiring harness, secure them in place with screws, and test the signals before finalizing the installation.
