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.
