Can't find a diagram right off, Tail lights get power through the headlight switch. Fused tail circuit feeds through headlight switch.
I like to put a tone on the wire and follow back to headlight switch with inductive amp. May go through a security circuit, causing the lights to flash in alarm condition.
If you find a diagram online let us know.
The Service Manual should have electrical diagram. The Manual will save you time and money for as long as you have the car.
