20.2 – Now solder the two conductor white wires to the under –side of the heated bed where
it’s marked “V+” and “V-“. Before soldering the wires in, you may wish to intertwine them in order to
make the wires easier to manage.
Figure 96 - Thermistor wires intertwined for easy management.
20.3 – Now you’ll want to take the four conductor 18ga cable included in the kit and solder it to
the Heated Bed. Each pair of 12v terminals provide power to half the heating element on the board.
This is why four wires are required. Trim the wires back only about ¼” inch and insert them from under
the board. The colors I used were red/black for +/- on one pair, white/green for +/- on the second pair.
20.4 – Re-install the heated bed, routing the four conductor cable & thermistor cable though the
slot cut in the base as shown below. You may want to add a small piece of heat shrink tubing to neaten
the appearance of the wiring.
