For those that run cables are those even legal? Have you ever had it commented on at tech? My NHRA rule book states all rod or cable must be of 5/16 diameter most of those look like 1/4 or less. Or is it the fact that the cable is just ancillary make it not relevant. I just looked at this rule for one of my cars I was working on a couple weeks ago. Using a shifter cable would be easier plus I have them laying around,but they aren't 5/16.
The rule book is concerned with safety people being able to shut everything down at the rear of the car, in the event of a crash.. Beyond that, they won't or shouldn't care.
If you back into a wall at speed and tear it all up, probably doesn't matter if you have a cable or rod at that point.
Dragsters have had the master switch up by the battery forever, with a cable to the rear of the car to operate it.
High amp remote relays are becoming common now with the pushbutton/mushroom head switches being used to control them. Takes some specific switches and wiring to be able to control it from 2 locations - unless you use your old master switch set up to control the relay, rather than to function as the high amp connector. Modern and Speedwire and others offer these systems.
