Wiring Parts Needed to Power 3rd Brake Light on 2020 Toyota Tacoma Topper Shell
Question:
Hello, I’m inquiring if you might have a wiring harness for a 2020 Toyota Tacoma but for a topper shell to tap into the brake light. Thank you!

We definitely have the wiring parts and connectors to help you out but you will need to do some splicing to accomplish this as there isn't a plug and play type adapter. Here are the parts I recommend:
- 3rd Brake Light Logic Module # PP20-702
- Pollak Complete Assembly 2-Pole Connector # PK12200
- Deka Heat Shrink Butt Connector Kit # DW05744-5
- 18-Gauge 2-Wire Bonded Parallel Conductor Wire # SWC97FR (sold by the foot)
The Logic Modul connects to your turn signals and feeds the brake signal you need for the topper shell on your 2020 Toyota Tacoma. Then you just need the Pollak connectors for a quick-disconnect if you ever take the topper off, the butt connectors for your connections, and then additional 18 gauge wire (if necessary).
This setup does require you to cut into your OEM wiring on your truck to make the connections to the turn signals. You can avoid this by installing the Curt T-Connector # C56349 and then pairing this with the light module and a 4-Way Harness like the Hopkins # HM38138 but this route will be a bit pricier and you'll have to cap off the running light wiring for the Hopkins connector since you won't be using it.
