Parts Needed to Convert 4-Way to 7-Way and Activate 12 Volt Accessory Circuit

Question:

I have a Jeep Liberty tow vehicle that has the 4 way flat plug for turn/brake/taillights. My rv has a 7 way Pollak 12-705 connection. I am looking to add a battery maintainer to my tow vehicle while towing. I found the battery maintainer but now I need an adapter to change the 4 way tow plug into a 7 way tow plug. Recommendations please.

You'd want the 4-way to 7-way adapter part # 37185 which will convert your 4-way to a 7-way like you are wanting and then to activate the 12 volt accessory circuit you'd need to run a length of 10 gauge wire like part # 10-1-1 which we offer by the foot through a breaker like # 9510 to the vehicle's positive battery post and you'd be set.
