While we recommend having a professional carry this out, here’s a general breakdown of the steps:
1. Stretch out the wire and use wire cutters to cut it in the middle. Strip the insulation from the cut ends of the wire, so there’s an inch of exposed bare wire. Pull apart the leads and separate them by four to six inches.
2. The wire you use for the circuit should be similar gauge and construction. Cut a length long enough that you can place the light at its destination.
3. Separate the wire leads and strip one inch of insulation from each end. Slide two-inch pieces of heat-shrink tubing on the new wire’s leads. There will be two pieces on each end of wire.
4. Twist the old and new wires together for a continuous length. Heat the wire with a hot soldering iron at each joint, and then apply the solder until it flows into the joint. Remove the iron and repeat this step.
5. After the joints cool, slide the heat-shrink tubing onto the joints and use a blow dryer to direct heat onto the tubing to shrink it.
6. Test the operation by plugging in your low-voltage system, and then place the lighting fixtures and wire.
