CAUTION
Avoid wiring damage. Do not cut the orange wire flush with the wiring loom. Doing so will
damage other wires in the loom.
1. Disconnect the orange wire from the alternator battery terminal. Splice sufficient gauge
wire to the orange wire and connect as shown.
2. The splice wire must be a minimum of 8 AWG.
3. Insulate and seal the end of the wire with liquid neoprene and heat shrink tubing.
