Brake Controller Recommendation for 2003 Chevy Silverado 1500
Updated 06/23/2026 | Published 06/21/2026
Question:
I have a 2003 Silverado 1500 without a current tow package. I have a 4 pole flat trailer harness currently installed. I now will be towing a travel trailer and need a 7 pole round to connect to trailer as I will be adding a Tekonsha P3 trailer brake. What harness/wiring accessory will I need to accomplish this? I would like an an adaptor that has both a 4 pole flat and a 7 pin round at the connection end.

Hey Ryan, since Tekonsha is no longer in business we can't get the P3 or the install harnesses for it any longer but we can still help with a brake controller. I really like the Redarc Tow Pro Link part # RED57AR which installs by plugging inline with the 7-way and you can control it with the included remote. What are you planning on towing?
