Before you get too excited about pulling the turn signal switch you should check the three wires that power it. On the column the connector has a white, purple and brown wire all from the fuse panel. The white is for the brakes, the purple is for the turn signals and the brown is for the hazards.
The brown wire has power full time, the white is the powered when you step on the brake pedal, and the purple is powered when the key is on.
The tail and front parking lights are powered by a brown wire off the headlight switch, but it goes to the rear harness for the tail and license plate lights.
If you get power on these wires then you can check the turn signal switch for continuity with an ohm meter.
on the harness going up the column to the TS switch check
The white wire to the yellow and dark green wire for zero ohms.
The hazard wire, usually brown, to the yellow, dark green, light blue and dark blue wires for zero ohms. With the hazard switch pulled.
If you want to check the turn signal wiring do the following
Check the purple wire to the light blue and yellow wires to the purple wire with the TS lever in left turn. Hazard switch pushed in.
Check the dark green and dark blue wires to the purple wire for zero ohms with the TS lever in the right turn position.
Sometimes the wire colors do not match but they are almost always in the same positions.
On one end you have the black horn button ground wire.
Next to it is the left turn,light blue wire,
next is the dark blue right turn wire.
then the brown hazard wire.
then the purple wire for the L and R turns.
then the yellow wire for the left turn
Then the dark green wire for the right turn,
and finally the white wire for the brake lights.
I'll double check these and post the diagram.
