This is strongly discouraged by Hunter for the following reasons:
- It is unlikely that the pre-existing wire meets the specifications for gauge, twist, and solid copper.
- Pre-existing wire will not be color-coded correctly for the decoder wires.
- Pre-existing wire may have invisible problems (shorts, breaks, increased resistance, or damaged insulation) that will be inherited by the new installation.
