1. Strip cable jackets to expose 1 foot of conductors. Lay the two cable conductors over each other and stagger cut so that splices are not in the same location. Strip off each conductor primary insulation to insert in ½ the length of the Butt Splice connector.

2. Slide the large heat shrink tube that will cover the entire splice over one of the cables so it is on and out of the way.

3. Cut the small heat shrink into lengths that are at least 2 inches longer than the Butt Connector and slide these over one set on each conductor prior to installing Butt Connectors. Slide over longest length of conductors so they are out of the way of crimping and soldering the Butt Connectors.

4. Drill 1/8” hole in the center of each Butt Connector for soldering operation upcoming.

5. Position Butt Connectors on one cable conductors and crimp in place. Then position the other set of conductors in the Butt Connectors and crimp in place. Using a Solder Iron or Torch heat source carefully heat up each Butt Connector and solder using Typical Electrical Grade Solder. Allow to cool or use a Sponge and water to cool quicker.

6. Using 130C self-vulcanizing rubber tape wrap each butt splice connection starting ½” up conductor from Butt Connector end and end ½” up the conductor on the other end of Butt Connector for all Butt Connectors. Slide heat shrink over each splice connection centering heat shrink over splice. Using Electric Heat Gun or Torch carefully shrink heat shrink starting in the center of each heat shrink & moving outward as it shrinks completely. When glue begins coming out of each end of the heat shrink stop and allow to cool. A water wetted sponge will speed cooling.

7. Using remaining 130C rubber tape cover entire exposed conductors as remaining tape allows to make assembly near the diameter of the cable outer jacket. This is used to support and contain the conductors and splice and build up the diameter where the cable outer jacket is missing.

8. Slide the large heat shrink that is over the entire jacketed cable over the splice area centering it over the splice area. Again, use an Electric Heat Gun or Torch to carefully shrink this heat shrink to the cable. Starting again in the middle of the heat shrink and working out both ways shrinking slowly until glue begins to come from both ends of the heat shrink. Allow to cool completely before moving. Again a water wetted sponge will speed this process.
