Step 5Sew conductive thread leads
The two switches you made in step 2 need to be attached, in parallel, in between the two remaining connections of the motor and power source. We'll put each on the end of a strip of fabric to which we've sewn conductive thread. Since the conductive thread isn't insulated, you have to be sure each one doesn't touch its neighbors or you'll get a short.
First roll a bobbin with about ten feet of conductive thread. Do this by hand, as the conductive thread likes to fray. It's also thicker than normal thread, and you may want to loosen your bobbin tension (see second pic's notes). You may need to loosen your upper tension a bit, too, as you want the conductive thread to stay on one side of the fabric and not get pulled through. See the notes on pic 4.
Once you've got the bobbin in place, run two lines of stitching along your scrap fabric strips. Run one line on each side in case the fabric gets folded up inside the pillow. Leave about 6 inches of thread at each end of the seams.
Make two of these, one for each switch.
