Okay guys. Now I am not the sharpest tool in the shed when it comes to electrical. I have a Sahara wired with a 4 pin trailer setup. I upgraded my ATV trailer and it has electric brakes and needs the 7 pin (round) set up. So I buy the mopar 7 pin wire harness. All cool so far. I look at the directions and it looks like a comic book... bad.... no words..... funny pictures..... so the very first part I am stumped at is how it connects to the rear light. Since I already have the 4 pin (and would like to keep that active for my other little trailer) I am not sure how to plug that in. Anyone run into this. A photograph would be better than the comic book that came with my harness.
