I am having some trouble with wiring a flat 4 pin trailer plug in my 2000 jeep cherokee sport i have ordered twice now for the trailer wiring easy hookup but I keep getting the wrong plug ends so how do I wire it in without the easy-to-use plug in set and just use jumper connector if tried but the brake and turn signal are two different plugs and when I jumped the wire on both of them my turn signal made the other brake lights blink please help me

 

Did you purchase the same brand/model of inline adapter both times?

 

The problem is your Jeep uses separate wires for brake and turn signals. You need a specific converter box to combine them for the trailer. Don't just jump the wires together. Get a "tail light converter" or "wiring module" for vehicles with separate brake and turn signals. It will have the correct plug for your Jeep's taillight harness.
