Why is my Autowbrake brake controller engaging when my turn signal is on. My trailers left brake engages when the left turn signal is on and the right brake when the right turn signal is on.

Since the Autowbrake Electric Brake Controller # 3430001 ties into the turn signals it's most likely thinking the signal for the turn signal is actually the stop signal and is activating the brakes. Since there really isn't any troubleshooting that can be done with the unit itself the only thing you can check is the wiring. The first thing to start with is the ground wire to ensure you have a strong corrosion-free connection to the trailer frame. A bad ground can cause all sorts of issues with electronics.

From there you'll check each wire connection to ensure that they're going to the correct wires on the trailer and that there's no loose or corroded connections. If that doesn't work then the unit itself might be faulty and in need of replacement.

Answer 7

You are correct you will need the 4-pole flat part #118727 and the part #etbc7 to get a 7-way on the back of the Jeep to power the Autowbrake part #3430001. The blue wire from the ETBC7 to the front of the vehicle is not needed because the Autowbrake…

Hey Michele, since you have replaced the Autowbrake part #3430001 already the issue has to be the wiring of the controller. I would recommend going over all of the connections that the brake controller has made to your trailer. Since it's not…

The Autowbrake Electric Brake Controller part #3430001 simply requires an active battery charge line circuit which is a wire run from the trailer connector to the battery to provide a small charge for the trailer battery while in tow. This wire…
