Recommended splicing method - Solder (For 16 AWG/1.0 and Smaller Diameter Wire Only)

NOTE: Cut and splice one circuit at a time noting the original wire to connector pin locations. This will avoid miss-connections.

1. Disconnect battery ground cable.
2. Strip wires to appropriate length.

3. Install heat shrink tubing.
4. Twist wires together.
5. Solder wires together.
   NOTE: Use rosin core mildly-activated (RMA) solder. Do not use acid core solder.
   NOTE: Use heat shrinkable tubes marked with ES-1 (16-22 AWG/0.5-1.0mm) or ES-2 (10-18 AWG/0.8-5.0mm) to seal wire splice.

6. Evenly position heat shrink tubing over wire repair.
   NOTE: Overlap tubing on both wires.

7. Use shielded heat gun to heat the repaired area until adhesive flows out of both ends of heat shrink tubing.
   NOTE: On smaller wires, use pliers to gently squeeze the ends of the heat shrink sleeve (while heat shrink is still warm) to ensure a tight fit and close any air gaps
8. Reconnect battery ground cable.
