using a test 12v test light to see which wire becomes hot when the parking lights are on would be the way to go. also there would be verification as to the correct wire for p lights. kg here goes! the main wiring harness that comes back to the 7 prong trailer plug is what im talking about!the harness comes back and ends with a square female end plug then your round 7 connector plug plugs into that if you seperate this plug the end that you unplugged and are holding in your hand is the piece your trailer plugs into. now if you go back to the part of the plug thats still connected to the trucks harness can anyone tell me which female posistion on that plug is for the park lights i plug my trailer in and have 4 ways brake lights reverse lights signals but no park lights! im wonderiing if i have a bad wire coming back the harness somewhere and i need to now what wire it is in the harness. a wiring diagram would be very helpful. thanks too anyone that replies. .

thanks nosey but im looking for info on the square plug of the trucks harness that connects to the 7 prong male end that then connects to the trailer plug sorry i didnt comprehend the question. i understand what you are talking about now. the black wire with the orange stripe in the trucks harness is the parking light wire going into the 7-way socket. if you have the factory supplied brake controller harness in your glove-box rip open the package and look at the sheet of paper inside. it shows the plug that you are talking about and the wire colors going into the 7-way female socket. .
