Parts Needed to Install Prodigy P3 Brake Controller in 2018 Jeep Wrangler Unlimited  

Question:

I already have the P3 controller but I left the harness on my last vehicle, can I get just the harness for the controller? seems a bummer to have to buy the entire controller again.

Since the 2018 Jeep Wrangler does not come with factory brake controller wiring you'll have to hardwire in your P3 part # 90195.

You will need to start with a 4-way (if you do not have one). For that you would want the # C55124.

From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.

I see what you mean now. The replacement connector you are looking for is the part # 20127 for your P3.
