What if Tach wire becomes disconnected?

So just thinking- what if a vehicle that is programmed for tach sensing is in for another repair- and the tach wire is removed and not re-installed- or it is pulled loose, or cut unintentionally?  Does the remote starter now crank for 15 seconds- even though engine starts in first second? - does it shut down- not knowing it was started, then try again two more times?  This would be tough on a starter motor- does anyone know of instances where the vehicle's starter motor was destroyed by the remote starter?  perhaps in this manner?  I always try to "hide" the tach wire in other conduit, or make it as reliable as possible- but often wonder what other mechanics might not be as considerate- most mechanics I know hate aftermarket equipment and would like to disable it as soon as they see it.......thanks

The Audiovox stuff I install limits the cranking to six seconds, I believe. And three attempts to start, as you said.

But now that I think of it, on the cars I've seen where the tach wire comes disconnected, the car seems to only crank for about one second on each attempt---not sure why.

When a viper or autostart see no tach signal when cranking they shut down.

Some brands of remote car starters the starter stays engaged with the engine running when it does not see the tach signal.It make a lot of noise when this happens.
