First time doing this, don't want to burn house down. The brown bundle is coming from thermostat, the white bundle I suspect is coming from A/C unit. Do I follow these steps?
- Find a scrap piece of 18 gauge wire
- Unplug furnace
- Strip the end of clipped blue wire in furnace
- Twist blue wire to scrap wire and cap with wire nut
- Wrap scrap wire around C screw on the left
- Plug in furnace
