i just bought a novaand it has no wiring in it. it doesnt have a neutral safety switch or a steering column connector for the turn signals, horn and other stuff... I'd like to have extra toggle switches, one since my steering column has no horn button and for the turn signals as well. plus it has a universal ignition tumbler that is installed in the dash. so after i get a wiring harness or make my own, will i necessarily need an NSS if I'm only using it to drive to a shop and parts store?
