Are you asking for a wiring diagram to wire your ride with....
Turn sig, running lights and brake lights utilizing one single filiment bulb with two wires coming out of it?

or

one dual filiment bulb with two wires coming out of it?

With a single filiment bulb, it's almost impossible to do without some sort of specially made electronic controller that would control cross/back feeding.

It is possible to do it with a single dual filiment bulb, using one filiment for the running lights and the other to control the turn, flasher and brake functions..... but it requires 6 relays and a DPDT toggle switch (DPDT switch is used to turn on the turn signal)

In my system I use a single flasher can, 1- DPDT toggle switch for the turns, 1- SPST toggle to control the flasher, normal brake light switch, 6- bosch style relays.

I've attached a working diagram and the type relays I like to use. The relays are out of a junked late model Chrysler.

2 wire bulb

the hot goes to the center spot on the bulb and the ground goes to the copper housing... a bulb can be used for many purposes but the wire is still the same.

Just to clearify.....

There are plastic light sockets that have one wire and it's the hot connection and they will have a metal tang somewhere on the securing fingers that is the ground.
There are plastic light sockets that have two wires, one for hot and one for ground.
There are plastic light sockets that have three wires, two for hot and one for ground.

Metal sockets.... the grouind is usually the housing of the socket and depending on the type, 1 or 2 wires, the wires are normally the hots
