The easiest solution would be to add a junction box like with the part # 277-000141 to your trailer wiring for the install of the Autowbrake part # 3430001. While it does require cutting the 7-way wiring it will give you an easy way to install the brake controller plus gives you the benefits of having a junction box. Basically you'd trace the 7-way wiring of your trailer from the connector back till you find where on your trailer you'd want to mount the box. You'd cut the wiring there and then wire the trailer side wiring to the correct posts of the box and you'd be set.

To splice in the wires of your trailer to the junction box all you'd need is ring terminals to go from the wiring to the posts of the box. You'd need 4 of the larger gauge ring terminals part # 44-5310A and 10 of the # DW05702-1 and you'd have everything needed to make the connections.

Between the bolt holes of coupler #CT-3001-Z I measured the same 3-1/16 inch. They're also 1/2 inch holes like yours. From the top to the center of the holes I measured about 1-5/16 to maybe even 1-3/8 inches. With that being said measuring from…

Answer 3

The Autowbrake brake controller part #3430001 that you referenced draws up to 15 amps. It's only going to draw amperage when the controller is activating the trailer brake so it would not be something you'd need to install an on/off switch on…

The Autowbrake #3430001 is a great choice! To add a 7 way to your 2017 Dodge Grand Caravan you'll want to use the #ETBC7L, since it doesn't require the wiring of a brake wire into the vehicle like the #ETBC7. You will still need to run a wire…

Answer 6

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…

Since you confirmed the Autowbrake Electric Brake Controller #3430001 had 12v power running to it the only only other thing to really check would be that the rest of the 5 wires were spliced into the proper circuits. With proper power and ground even…

As long as the 7-way was installed correctly with a circuit breaker protected connection to the tow vehicle battery, the #3430001 Autowbrake Brake Controller you mentioned will work just fine. A single axle trailer will only draw about 6 amps at full…

You are going to need our 7-Way RV Upgrade Kit #ETBC7L to tow a camper having a 7-way behind your 2017 Subaru Outback with a 4-way flat connector. The Adapter #HM47365 you found does go the opposite way from what you need. The charge line included…

I would first encourage you to test the 7 way connection on your 2012 Lexus RX 450h and make sure that the issues aren't stemming from some sort of damaged wiring/connection. We don't have any confirmation that the Tekonsha Prodigy RF will or…

Answer 11

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…

Answer 12

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…
