How do i wire this up on my trailer I have the basic 4 prong wiring harness Ther are 2 wires that come out of the back of the light red and black gronding by supplied hardware. If red wire is wired into the brown and yellow wire saying black is power wire wired to the brown wire when you turn the turn signal on and push on the brakes would the light on the other side illumiate as a stop light or should it stay as just a running light

What you are going to need to install the Trailer Turn Signal and Parking Light # MC32AB that you referenced is a Vehicle to Vehicle Taillight Converter # 118158. This product will wire in on the trailer wiring and will split your tail light circuitry so that the blinker and brake light circuits will be separate.
Here is how it will wire in. You will run the ground wire from your trailer 4-way to white wire of the box, the left turn/stop wire to the yellow wire and the right turn/stop wire to the green. Note that the tail light wire will not run to the box.
From the output side of the box you will run the green, right turn signal wire to the either wire of the # MC32AB on the passenger side of your trailer. The red wire will be run to your brake lights. The yellow wire will be run to a wire of the # MC32AB on the driver side of your trailer.
The tail light circuit from your 4-way that did not go through the converter box will be run to the black wire of the # MC32AB on both sides of your trailer.
