Newbie Help--Bridge Pickup replacement

Ok...I have a fender american deluxe, 2005, with the S-1 switching system. I've replaced the neck p/up.

Now I'm replacing the bridge SCN with a Fred Stuart Lapwrap.

Thing is...the SCN that I am replacing has three wires, black yellow and green, the Lapwrap has two, yellow and black.

The yellow wire on both pickups I can account for, that's fine, the go to the volume pot. On the SCN pickup both the black and the green end up soldered to the tone pot.

The black on the Lapwrap...I don't know if that's a ground wire or if that is the tone wire.

There's also a solder point on the guitar itself underneath the bridge where it looks like three black ground wires come together. Should I just solder the black into there and forget about it?

If the black wire on the Lapwrap pickup itself its not for tone control, does that mean I run the Lapwrap wide open on tone?

If its for tone, how do I ground it? Does it have a dual function as a ground into the tone pot as well as tone control?

I guess I could solder the black lead into the grouping directly under the bridge or straight to the tone pot.

Not sure how to proceed.

Any general p/up soldering advice? Anyone?

Bueller?

Did you ask Fred?

Because of the S-1 switch on the backside of the volume pot, the designers moved the "star ground" from the back of the volume pot to the back of the tone pot. It is "common ground" the way the diagram appears to me.

I would just run yellow to yellow and black to black, and in one of the 2 S-1 positions it should function like a conventional 3 way Telecaster. I'd like to refer you to one of Fender's wiring diagrams but there must be 6 Am Deluxe diagrams on their site and I don't know which version you have.

I ran yellow to yellow and black and black--the black went to the grounding screw right beneath the bridge.

And everything seems to work ok, tone pot manages tone and volume pot manages volume level, but i think its out of phase with the neck humbucker (sounds nasally, relatively low output), and there's a bit of 60 cycle hum.

I'm going to flip the magnet in the neck humbucker and see if it clears anything up.

But yeah, soldering it to the ground screw 'clump' of wires seems to be the way to go. I can't see any other way to do it, other than soldering it straight to the S-1.

Oh, and I have a 2005 american deluxe, btw. Yeah, they have a bunch of diagrams on the fender site.

Someday, I will be finished with this. Someday...
