Some wires will be missing (for example the wires from your windshield wiper pump to your switch, and to your windshield wiper motor to name 1 set). Second, you should look up their manual for your car model specifically because it will be much more helpful to rewiring your car than the general manual or their customer no-service. Third, their crimps for the headlights, volt regulator etc. suck. Positives: comes pre-separated into sections to run the wire. There is extra length of wire so you won’t run out of it.
