Datasheet

If you have multiple colors of wire, the tradition is to use black or green for ground and red

or another bright color for positive. I used red and black wire. This wire should be relatively

thick, since it has to carry several amps of power. I used 20 gauge stranded wire.

Prepare your two pieces of wire by stripping off about a quarter inch of insulation. You'll be

putting each wire through the hole in your barrel jack's terminal, wrapping it around, and

soldering it.
