I understand what the problem is I just figured this would be the easiest route. Seeing as to how you want to go this path heres the way. Contrary to what 67chevyredneck has stated, If your truck came with the light duty trailer harness, They were blunt cut and are fully intended to be spliced into. You stated there are 4 wires in that blunt cut harness correct? They should be brown, yellow, dk. green, and white. The white being the ground, brown tail, yellow for left turn, green for right turn. If you are using the seven pin flat pin round connector, you can just run those four into it, leaving the other 3 unused. the other 3 would be for 12 volt supply, trailer brakes, and aux/back up lamps. If you are wanting those 3 to work as well, then you will need to run a seperate brake controller and run a lead back to your plug, and run seperate leads from the fuse block for the 12 volt supply, and a lead for your aux/ buckup lamps, from whatever location, if you chose to use them. The blunt cut harness was more intended for people using smaller trailers with just a flat 4 pin connector. As you had guessed in your first post, most people were not using these light duty trucks with larger trailers that require the larger plug. And fyi if you use the 7 pin there are colors printed next to each pin on the back side of the plug. Don't mach wires to whats printed on the plug. they are not right. Best thing would be to google a pic of the trailer plug pins (truck side) and go off that.
