What post on Toad connector for trickle charger?

I had a "Rvibrake Towed Battery Charger TBC-12014 - Battery" installed on my toad to charge the battery while towing. I noticed that the light on the charger is not on when connected to my Thor Axis. I suspect they did not connect the 12v to the right post on the toad plug. I know it's not working because after a full day of towing with my brakebuddy running, dead toad battery. Have any of you done this? Can you tell me what post is the 12v on the Axis? As always any help would be great. Thanks

I always thought pin 4 on a 7-way plug was the 12 VDC pin. Did you verify the 7-way was fully wired and not just wired for lights and brake lights?

Pick up a 7-wire circuit tester it will tell you which wires are out.

Our 7-wire plug was all messed up from the factory.

This website will give you more info than you are asking as far as wiring: https://www.etrailer.com/faq-wiring.aspx

The tester Jamie referenced is the best way to check that the factory wired the plug correctly and completely. Sometimes they only wire the lights and have the wire for the power capped off. You might have to finish having the plug wired. But using the tester will be the fastest way to check what you have and don't have.

... and don't forget, one of the pins is for ground (pin 1 I think).

Attached is a PDF that shows all the various plug configurations on both vehicle and trailer (TOAD) sides. The pins aren't numbered; however, they can be referenced by the location of the keyway.

Towing a 2014 Hundai Elantra

This is my first trip out with the Elantra I bought to be my toad. A thing I noticed at a rest stop is that the push button start accessory position (that provides power for the Apollo brake and transmitter) shuts off after one hour to save battery. Luckily, the steering wheel doesn't lock when this happens. I checked with Hundai, and their customer care referred me to the dealer that referred me to them.... So I ended up wiring an additional accessory outlet direct from battery yesterday. All lights powered from RV. Apollo brake system is the only thing using battery... I did install a battery "maintainer". Comments/ advice?

Agree ... I always carry this with me in the motorhome.

One thing I did find out the hard way. The head lights on my toad (2016 GMC Terrain) go into "Auto" mode every time the car is turned on (ACC). This means that when the sun light is dim enough the toad head lights will come on. Headlights come off of the toad battery not the RV. Only the toad tail lights come off of the RV battery. So.... every time we were towing at dusk or on cloudy/raining days, I would run down the toad's battery...doh! Trickle charging is evidently not enough juice to keep up with what the toad headlights draw. So I made a simple procedure change to turn off the lights auto mode after turning the key to ACC position every time. It's the simple things right!
