Slip heatshrink over wire and insert wires into

butt splice. Keep heatshrink away from joint until

after soldering is complete and has cooled.

Crimp both wires to the butt splice using indent

type crimpers.

Solder the wires to the butt splice. Ensure that a

good connection is made.

Wait for the butt splice to cool, slip heatshrink

over the joint and heat.
