Most of them use a wiring harness which is made on a large board with what looks like finishing nails in it. The nails are placed so that the different wires can be woven around them and extended to the proper length. Those boards with the wires on them are how the original plastic ty-wrap came about. We used to ty the cables with a real tough string and the knot had to be tied a certain way to keep from coming untied. Technology has taken over and they now use what is called a ty-wrap gun putting a regulated amount of tention on each wrap. The person building the harnesses works off of a work order that tells what you ordered when you ordered from your dealer. When he is all caught up with orders that people have submited, he builds the best sellers that a dealer may want to leave on his lot for you to look at. Or he may build a trailer that is easy for a dealer to add something to.... This concludes the lession for today on trailer building... Have a great day...JB
