Saturn Territory mod on a single 3-way switch

Another thread from me today...

Well, the topic lines pretty much sum it up - any idea where to find tutes on how to do the territory mod with a single 3-position switch? The two-switch method is messy and I'm looking at doing a clean terriotory mod.



I tried the switch once, but it didn't work, due more to my ignorance than anything else. I've removed all the connections, re-read everything and I'm trying it again.

To ensure I'm actually doing the right thing, could someone confirm that the following diagram is the correct way of installing the switch? I know bugger-all about electronics, bar what I've worked out when modding consoles, so if someone could confirm I'm doing the right thing, I'd be a happy little modder indeed
