The resistor doesnt care about what kind of an ignition switch you have. It's to provide sufficient current to initially excite the alternator but then limit current and drop sufficient voltage so the alternator dont backfeed the ignition coil so she quits when you turn off the key.
Like I already said, I use a 10 ohm or larger resistor there instead of a diode as it serves a DUAL PURPOSE to prevent backfeed PLUS it drops some voltage and limits some current.
It dont hurt if you use a larger wattage resistor (like a 10 or even larger watt, 10 ohms and higher) and it may even be easier to wire as it may have bigger leads
The 10 ohms 5 watt you mentioned will probably work fine, if it gets too hot it will open in which case the alternator may not excite butttttt its such a cheap and easy fix, just replace it with a 10 watt or more but I doubt the 5 watt will go bad.
