I am splicing a switch into a wire in that sends pulsed speed signals in my car. I used AWG 24 telephone wire, solid core. Since cars vibrate, I used 2 wire conductors for each end of the switch.
Would I be better off re-wiring using a single stranded wire rather than 2 solid wires? Any issues in using 2 wires in each direction? Should I worry about any signal loss issues?
