Wiring Experts I need your help!

To jump to the wiring question, scroll down to "Question" near the end.

For a full history, read "Long drawn-out explanation".

Long drawn-out explanation:
About 3 years ago I put together a parts tele. It was pretty awesome. I did the Duncan vintage mini hum in the neck like a Fender Hot Rod. It was single conductor and sounded pretty wicked; amazing cleans and jazz tone to die for. It was pretty unbeatable and essentially perfection IMO. I had more trouble finding a bridge pickup to go with it. I just hated the hum of any single and I even tried the Pearly Gates for tele (which was close but no cigar). Eventually I decided to go with 2 minis using a conversion bridge (see pic below). Pretty drastic, I know, but remember -I LOVED the SM1n. I figured alnico was a must, so I bought the SM3 for the bridge instead of SM2 and a SM1n in 4-conductor.

Then I thought "what do I REALLY want on this axe?" The answer was multiple sounds for versatility, but single coil tones are just not my thing anymore. Can't stand the hum!!!
Bill Lawrence has been preaching parallel wiring instead of split for years, so I thought why not try it? When I realized that Fender S1 switches are available aftermarket and you can use them to replace mini toggles, I decided that would preserve the look of my tele, and I added the 4-way mod switch I have been using for years.

I tried to adapt the S1 for the usual Duncan mini toggle wiring, and it seems to have worked (read below).

Question:
My 4-way switch isn't working! Now I noticed that it is not he same lug pattern as the diagrams found online. It's as if it is offset, or viewed from above. I did my best to wire the thing accordingly, but no dice. I get the neck pickup alone in 2 positions, then both pickups on in the other 2. Furthermore the pickups are out of phase with each other!

How in the world can I sort this mess out? I have a nice diagram for the S1 which I made using MS paint but it's at work, so I can only upload it tomorrow. My 4-way is really odd, I will have to do the same and draw it so you can understand.

I really want this to work as I can already hear the great tones from the minis and the switching is so stinking easy and useful it's ridiculous! Thanks for your help!

Re: Wiring Experts I need your help!

Ok here's what I did:

It's just the standard series-split-parallel scheme adapted to the S1. The good news is that I think I found my answer to the 4-way. This diagram shows the lugs like my switch has, so I'll try it tonight when I get home.

I still need to figure out the phase issue when both pickups are on! If you know what to do here, please speak up. On a side note, I have no idea why my pic above is showing up as an attachment and I don't know how to remove it.

Ok, no replies -that's ok I figured it out but for posterity, anyone wanting to try this -it's a really powerful wiring scheme!

The S1 is an ideal way to get Parallel-Series in one push of the button. It's a lot like clicking on a boost pedal as you get 2 distinct outputs and all positions completely noiseless, onboard and passive.

I had the neck pickup ground lead going to the common ground on the back of my tone pot instead of the switch. I went too fast and assumed the pickup cover to be grounded was the -ve lead. My bad...

I can't actually tell if the pickups are in phase or not, but all 4 positions work great and there are 8 distinct sounds. I used 500k pots and a 0.22 uF PIO cap for what it's worth.

The classic tele spank of the bridge pickup is not quite there, but as everyone else says, the firebird style minis (which these are) really straddle the humbucker-single coil line. In parallel I find it is acceptably close. I think the SM1n has a tad more openness, where the SM3b is a wee bit congested like overwound pickups can be sometimes. The output when dirty is welcome however so I don't know if it's worth changing. I still need to play with pickup heights and setup the guitar better but overall this is a very worthwhile conversion.

Sorry Natman. I wasn't "blowin' you off", so to speak. I just didn't see this. Looks like you got it worked out.

Sweet axe, btw. :)
