It is certainly the way I prefer, and I've said so several times.  I've been running that way since 2001 or so; with an original
solenoid that lost some of it's smoke on the way home from VTR 2000.

Another benefit of this connection is that the solenoid on the Hitachi gear-drive starter draws a lot more current than the original
TR3 solenoid.  If you wire the original switch to the new solenoid, it may shorten the life of the switch.
