I just now received my tele SCN pickup set for my Mexican tele so that I can stop having such an awful hum and buzzing when I play loud. The only problem is that I have no idea how to install them. I though they would come with some pretty detailed intstructions but only a wiring diagram. Any help?
,thanx

Unfortunately, you will need a little detective work to figure this out. Let me first state that I built a Telecopy with SCN's a couple of years ago My "Proper" Telecopy. This is located in a different city from the one that I am in this week so I wouldn't be able to look "under the hood" of mine until next week. The SCN pickups have three wires; the one from the round pad (signal output), the one from the triangle pad (signal return), and the one from the square pad (frame ground). The usual AmDlx Tele has the S-1 switch for series as well as parallel when both pickups are selected. The Mexican Tele's do not. As a result, wiring for a standard Tele won't help (insufficient wires) nor will the wiring for an AmDlx Tele (too much switching). If you look at the Fender diagrams for the AmDlx Tele (010-1600/1602-xxx), you can decipher some things. The switching modes; www.fender.com/support/diagrams/pdf_temp1/telecaster/0101600_02A/SD0101600_02APg4.pdfThe pickup color code; www.fender.com/support/diagrams/pdf_temp1/telecaster/0101600_02A/SD0101600_02APg2.pdfThe neck signal output is white and the bridge signal output is yellow (see #18). The neck signal return AND frame ground (look at the jumper between the square and triangle pad on the back view of the neck pickup #10) is blue. Look at the wires connected to the back of the volume pot, there are five; the black wires from the bridge pickup, the neck pickup ("uh-oh"), the output jack, and the cavity shield lug wire. Hmm, that's only four. And, there was a definite "uh-oh". So, this means that, on this drawing (aside from the errors) the neck pickup has the following color code; White - signal output - round pad Blue - signal return - triangle pad Black - frame ground - square pad And, the bridge pickup has the probable color code; Yellow - signal output - round pad Unknown - signal return - triangle pad Black - frame ground - square pad For your Mexican Tele; Bridge pickup Black to ground Unknown to ground Yellow signal output to selector switch Neck pickup Black to ground Blue to ground White signal output to selector switch Use your digital ohmeter to verify which color wire connects to each shaped pad on each pickup. Two will come from the coils, and the third will come from the pickup frame ground.  |

For my SCNs, there are 3 wires from each pickup. The neck has a white for signal output and a black for signal return. This matches up perfect with my Mexican tele. The only difference is the third green wire. Should I just solder the green wire to the volume pot like the black wire?
The bridge pickup has a yellow for signal output and a black for signal return. This also matches up perfect with my Mexican tele. Also, the only difference is that 3rd green wire.
I know very little about guitar wiring and electronics, but I would like to get these pickups in very badly because I have been trying to find a solution for my Tele being so noisy for over a year now.

Absolutely! Again, connect this to the volume pot like the black wire. The wire colors may vary, but the pads on the pickups likely will not. It's the pads that matter since these are the internal/external connection points. The SCNs have the three wire interface which is crucial for doing series as well as out of phase wiring if so desired. The third pickup frame ground wire enables this with the frame connection separated from one of the coil leads (the way it should have been done from the beginning of electric guitar time). |

The third pickup frame ground wire enables this with the frame connection separated from one of the coil leads (the way it should have been done from the beginning of electric guitar time). So I should just solder the signal outputs and signal returns exactly like they are on my stock pickups, and as for the extra green wires, just add them to the back of the volume pot with the signal returns/grounds? That sounds good but now theres still something I dont understand. On the black signal return wire of my SCN bridge pickup, there is a lug for a scew to go through, and then from there, there are two seperate ends of the wire to solder. First off, why do you need a lug to go into the bottom of the cavity and does it go into the bridge pickup cavity or the control chamber cavity? Second, why are there two ends to the wire? I though I was supposed to solder one to the volume pot to ground it but what about the second end? |

Heres how the new SCN bridge pickup looks. You can see the black signal return wire that I am having trouble with.  If I had to guess I would say that the lug goes into the bottom of the control cavity (I have no idea why though, maybe so the grounds have a place to go so they don't build up on the volume pot and buzz), and the two ends go with one end to the volume pot like all my other grounds and the other end has to be soldered to the bridge pickup harness to create a string ground? Where ya at Chris? I need ya! |

Again, yes.
Uh, no.
Uh, yep'ish!
The lug connects to the cavity shield screw in an Am Dlx Tele (of which you have none - it's a Mex Tele), the end of the short black wire goes under the bridge plate (it's the bridge/string ground on ALL Tele's), and the end of the long black wire ties these points into the back of the volume pot, which is the guitar's system ground, which is connected to the sleeve (ground) of the output jack).
Most traditional Teles grounded the bridge/strings thru one of the pickup mounting screws to the black (signal return) wire on the pickup (I think). It was a simple way to ground the strings, but surely not the best. I always run a separate bridge grounding wire into my system ground in the control cavity.

So to create the string ground, I just strip off a long section of the wire, and tuck it under the bridge plate? (Or would you suggest doing that with a new wire that is seperate from the signal return?) Also, does the the cavity shield lug wire go into the bottom of the control cavity, or the bridge pickup cavity? I think its the control cavity but Im not positive. What is the point of the lug? If the cavity isn't shielded then wouldn't it just be going straight into the wood? |

3/4" going under the bridge plate (don't let it raise the plate up too much) would do. You need it to be near a mounting screw to ensure that the wire thickness goes into the wood to avoid a raised bridge plate. Conversely, you could perhaps use the lug but I don't know how you would attach it to the plate or pickup mounting screw against the plate.
Not in this case since the black wire is not the signal return, but already a grounding connection from the pickup frame.
Yep!
Since the SCN pickups are only available in the AmDlx Teles, which all have cavity shielding (your $1,000 - $1,300 does get you more "technology"), the lug is superfluous in the lesser priced (and shielded) offerings.

On my pickups, the black wire is the signal return because it has a triangle shape pad and the green wire is the frame ground because it has the circle pad. Thats cool that the American Deluxes have a shielded control cavity.Im guessing the pickup cavitys aren't shielded too. |

I finally got my guitar back from my local guitar shop where they checked over my wiring job and fixed any problems I had. I love the SCNs.
