PRS 5-Position Selector Switch wiring diagram
* * * * * * * * * * * * * * * * * * * * * * * * *  
5 POSITION PRS-STYLE SELECTOR SWITCH FOR 4+ HB's  
* * * * * * * * * * * * * * * * * * * * * * * * *  
 
. Seymour Duncan Color Codes:  
. Humbucker: Hot(+) to B; W to R; G to Ground  
. Upper coil: Hot(+) to B; W to Ground(Gnd) *  
. Lower coil: Hot(+) to R; G to Ground(Gnd) *  
. (Add SUFFIX to indicate which pickup:  
. N(Neck) or T(Treble))  
. (Example: BN for the Black lead on the Neck p/u)  
 
* These colors are correct for SD Hot Rails and  
Cool Rails pickups with SD logo right side up on  
coil nearest the bridge. Be SURE to check the coils on your guitar before proceeding and substitute color codes as needed.

5 POSITIONS:  
* * * * * * *  
. 1) Neck humbucker only:  
. + -> BN; WN -> RN; GN -> Gnd  
. 2) Inside coils in parallel:  
. + -> BT & RN; WT & GN -> Gnd  
. 3) Inside coils in series:  
. + -> BT; WT -> RN; GN -> Gnd  
. 4) Outside coils in parallel:  
. + -> RT & BN; GT & WN -> Gnd  
. 5) Treble humbucker only:  
. + -> BT; WT -> RT; GT -> Gnd  
.  
* * * * * * * * * * * * * * * * * * * * * * * *  
4 SECTION SWITCH (GN & GT connected to Ground)  
* * * * * * * * * * * * * * * * * * * * * * * *  
.  
. Switch section A: Switch section C:  
. Common -> Hot(+) Common -> WT  
. 1 (nc) 1 (nc)  
. 2 BT 2 Gnd  
. 3 BT 3 RN  
. 4 RT 4 (nc)  
. 5 BT 5 RT  
.  
. Switch section B: Switch section D:  
. Common -> Hot(+) Common -> WN  
. 1 BN 1 RN  
. 2 RN 2 (nc)  
. 3 (nc) 3 (nc)  
. 4 BN 4 Gnd  
. 5 (nc) 5 (nc)  
.  
Note: This is only one of several possible wirings.

Seymour Duncan: Black White Red Green  
Anderson: Red Green White Black  
DiMarzio: Green White Black Red  
Gibson: Black Green White Red  
Jackson: Green White Red Black  
Lawrence: Black Green White Red  
Schaller: Green White Brown Yellow  
PRS Neck: White <<<< Red >>>> Black  
PRS Bridge: Black <<<< Red >>>> White

to C, some of the switch positions will not work  
properly.)

Series/Out of Phase [Standard HB Linkage]**  
. A -> Hot(+); B <--> C; D -> Ground  
Series/In Phase [Non-Humbucking]  
. A -> Hot(+); B <--> D; C -> Ground  
Parallel/Out-of-Phase ["Dual Sound" Linkage]***  
. A & C -> Hot(+); B & D -> Ground  
Parallel/In Phase [Non-Humbucking]  
. A & D -> Hot(+); B & C -> Ground  
.  
** Normal humbucker wiring for full sound.  
.  
*** Alt. humbucking wiring for a thinner sound.

Final note: While this is an exact simulation of  
the PRS 5 position switch wiring, you may want to  
test out other linkages before soldering up your  
MegaSwitch. For Position 3, you may prefer the  
sound of the OUTSIDE coils in series, which is  
brighter and with more bass response (especially  
on a strat-style guitar). You may also prefer to  
substitute OUTSIDE coils in SERIES for the INSIDE  
coils in PARALLEL for Position 2. On a strat, I  
find that the outer coils have more definition  
than the inner coils, and that series linkage  
produces a stronger sound than parallel linkage.  
To experiment, get a package of microtest clip  
(Radio Shack #270-355) and try out different  
combinations of coils until you find the sounds  
that you like.
