Gas broiler stopped working

I unscrewed the igniter from the top of the oven, and removed the back panel of the stove. I had a friend in the back while I jiggled the two wires to see which ones they where. Then I had to use two pliers to pull the connectors apart. I tied a string to the two wires and pulled them out through the oven and left the string and tied the new wires to the string and pulled the new wires through the back of the stove, and replaced the back and screws.
