anyone have(or know where to get) a wiring diagram for under the dash of a 64 Chevelle? I need to know mostly the the brakes turn signals & tail lights. Thanks in advance, Jason

The 64 schematic can be found in the 64 Chevelle assembly manual. These are the better buy because the manual contains a lot of other information. Manuals can be purchased from any Chevelle parts supplier including Ground Up.
Schematics, by themselves, can also be purchased from a few places for around $5.50. Think the closest place to you is National Parts Depot in Michigan.
