I can not get humcanceling with Dimarzio EVO H-Bucker and TX Special middle SC. I switched the red and green wires. Still no noise reduction just a very small amount of diffence on the noisie between the mid pu position and the split coil HB and middle pu position. I have already checked all grounds. What gives? Should I switch the TX special hot and ground wires?

Before we all play Diagnosis Murder, let's clear this up. Please copy and paste this post into your reply, and then delete what isn't true.
To clarify:
You have a humbucker in the Bridge position, and a single coil in the Neck position.
If the above is true, then the guitar hums when:
1. You play "coil-cut" HB? 2. You play "full" HB? 3. You play "coil-cut" HB with "middle" Single Coil? 4. You play "full" HB with "middle" Single Coil? 5. You play "middle" Single Coil?

I'm leaving the very small possibility open that the middle sc and full HB maybe on but I do not have it wired like that and it does not sound like it is.

YES : You have a humbucker in the Bridge position, and a single coil in the Neck position. I meant "a single coil in the Middle position," but you've still grabbed my gist - my fault, thanks for keeping up. And there I was trying to be clever about this. Ok, if they're DiMarzio wiring, then swapping the red and green will only put the pickup out of phase with the other pickups. Here's Wolf's brilliant image explaining wiring colours. I suspect what is happening is that the coil being cut in the humbucker is the one that is reverse-wound from the Middle pickup. It's this reverse-winding that causes the hum-cancelling. It needs to be the other coil that is cut instead, so that the correct coil is being used in relation to the middle pickup. It is more than likely that swapping the wires of your full humbucker is still cutting the same coil. What you need to do is disconnect the black and the white wires of your humbucker. Then rewire the four wires of the humbucker so that: White is the "+" Green and red are soldered together, and Black is the "-" If I'm right in my guess at your problem, that should result in the correct coil being cut, resulting in a hum-cancelling sound. If not, then we'll try something else.

It is more than likely that swapping the wires of your full humbucker is still cutting the same coil... Naw, it'll cut the other coil now unless something else was changed. Problem is that the remaining coil is now "wound" the other way, so it can't buck hum. Does it sound noticeably thinner this way then the original? Can you do the screwdriver test? This works, and is probably best practice, but it can be a bit confusing for some. I think it's easier to just shunt toward the "hot" side rather than toward "ground".

No dice my friend. I even switched the the black and the white wires back and forth. No change. The split bucker and middle together is a little quieter than just the middle by it's self. Only a little. HB only position is working good. I used this diagram. I changed it for Dimarzio wiring of course. And changed it to running all the grounds to one point.Hmm could the star grounding be causing the problem? www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=1hum_2sing_1vol_1tone_5wayThis seems more difficult than it should be.

Oh also. White to ground sounds better than black to ground. I did green and red togther.

You know I think the HB is still on with the middle!! How the hell is that happening?

Found the problem. Out of all the different wiring diagrams for this set up. This is the one that worked. A had to add the jumper in the notes part. www.guitarelectronics.com/product/WDUHSS5L1101Wow I cant believe all the wrong diagrams out there.

Which is what you ultimately did, as per the Guitar Electronics alternative diagram.
In any event, problem solved, so it's all good!

Naw, it'll cut the other coil now unless something else was changed. D'oh. Ash is right. Glad it's fixed Spower.
