Hey, just keep the dash cam’s power down to 12 V and use a low‑drop‑out regulator so the old wiring doesn’t see spikes. Use automotive‑grade connectors and wire the camera in parallel to the existing fuse, not inline with the original wiring harness. Add a small inline fuse for the camera itself and make sure all grounds are solid – that’s the main recipe to keep the ’70s guts from frying.

Got it—will pick a regulator that tops the camera’s max draw, route the cable under the dash, and tape it with zip ties to keep it from snagging. If you want that ‘70s chrome to stay shiny, run the wiring through a small conduit or heat‑shrink tubing to avoid moisture, and don’t forget to seal the mounting holes. Give me a shout if the old paint starts to peel after the install.

Sounds good—I'll hit the clear coat and keep the wires wrapped tidy. Will let you know if the paint holds up or if I end up with a new coat of “rust.” Good luck to you too.
