Hi everyone,

I need wiring diagrams for my 1974 Century GS 455, Please anybody can help me with this?

the third generation of the Century nameplate ran from 1972-77 and actually takes over from the Skylark name on the mid size A-body cars. Skylark would return in 1975, but on the compact X-body Nova type cars.

while we don't have your specific year, we do have 1975 which should be very close.

Here is the overall diagram for the whole electrical system out of the '74 shop manual. The index page shows more detailed views that are also available in case you need them.

Try these done on a flatbed scanner at 300dpi instead of a cell phone camera.
