If you have never used the Pen Tool before then you might want to learn how first.
Before getting started, there are two things you must do. Select your foreground color, and make it a light shade of the color you want the wire to be, first try #8B8B8B. Next, select your Brush tool (B), and select about a 3px solid rounded brush. Leave all the settings at 100% and Normal. Do NOT Check off the airbrush.
a. Click only one dot (click and donít drag) at about 1/6 of the pallet down from both from top and left. Now at the top of the screen there will be a tool bar of options for the pen tool. Change the first setting to paths instead of shape layers. And if not changed, change the next setting to Pen tool, instead of Free Form Pen Tool.
b. Now move your mouse to about half the way down from the top and left through the pallet (the section where you want your wire to finish its first bend).
c. Now click, and hold.
d. Drag your mouse around the screen, and it will start to curve a line. That is your first curve.
e. Repeat this process for the ending point. If you still do not know how to use the pen tool, please look up a tutorial on the net, get used to it, and then finish the tutorial. If further assistance is needed, then please contact me.
