Hey Victor, thanks for reaching out!
To replace the power wiring that comes with the Tekonsha T-One # 118548 wiring kit for your 2018 Ford Focus you need the following:
- 12 Gauge Wire # 12-1-1 (sold by the foot)
- In-Line Fuse Holder # C58470-1
- 10 Amp Fuse (found in kit # PT52FR)
- Connectors # DW05745-5 and # 44-5356A
You can probably find a kit at your local hardware/home improvement store that includes the 10 Amp fuse and connectors and unfortunately there isn't a whole kit... view full answer...
