74 Dart Wiring Help Needed

"74 Dart wiring help needed" that's the car info and the switches are melting due to a short and are very worn. So new switches and wires should fix that I just need help getting my hands on a kit that'd do what I need done and my suspension is worn out I replaced the shocks and that had helped a lot but the car still leans a lot, I adjusted the ride height and its level but that's the extent I've gone as of yet
