7. If four wires enter the splice pack, go to step 8.
If five wires enter the splice pack, two closed-end connectors and a 16 gauge jumper wire are required. A
closed-end connector can only support four 16 gauge wires. The jumper wire will be installed between the
two closed-end connectors.
7.1
Cut an approximately four inch length of black 16 gauge wire and strip both ends approximately ½
inch (13 mm).
7.2
Splice two of the wires from the splice pack with the jumper wire.
7.3
Splice the other three wires from the splice pack with the other end of the jumper wire.
7.4
Insert both sets of spliced wires into closed-end connectors. Ensure that all wires are fully seated
into the closed-end connectors and crimp using tool DKIOCHA17003-3.
7.5
Using a heat gun, carefully shrink the closed-end connector until gaps are removed and a protective
gel seals the wiring. See Fig. 5.
