Install 11mm purselock just below M3 Clamp as shown on
picture. Reason for purslelock is to keep wires together. 
Wires need to be controlled to prevent pinch points when
B-Block is installed.
11mm purselock p/n:4-049-281-01
Route all cables through the “C” cut-out in the duct cover. The 11mm 
purselock should be BEHIND the “C” cut-out in black plastic duct cover.

CAUTION
: Route Upper Harness cables on the SIDE of 
the duct cover. Keep cables away from FRONT of  
the duct cover. ALL cables must not be routed in the 
front of the duct cover because of pinch points 
created when B-Block is installed.
CAUTION
: Make sure Upper Harness Cable is NOT 
routed in FRONT of the Duct Cover. This causes 
Pinch Point when B-Block is installed and can 
damage cables.

Apply one loop around cable above ferrite core with
C-shield M3 Clamp. Reason is to hold ferrite core
steady during transportation (prevents excessive
movement).
Route wires UNDER AGA Board (on chassis assy).
Connect CN8005(10P), CN8003(40P w/ferrite core).
CAUTION
: Make sure cables to not bind or pinch
between plastic PWB support peg when inserting
chassis assembly.

Install M3 Clamp and 3x12mm screw on optical block.
Dress C to GTA connector (p/n:1-910-021-69) as shown.
CAUTION
: Keep wires of 1-910-021-69 as low as possible.
M3 clamp p/n:2-594-860-01; 3x12mm p/n:7-685-648-71 
Dress Wires from Speaker, Speaker Grill and Side inputs in purselocks as 
shown. Speaker harness with ferrite cores are dressed in M4 Clamp and
purselock. After all cables are routed through slot in bottom cabinet, 
apply himelon tape to seal-off cables. Himelon will prevent cables from
coming out of slot; pinch point for rear cover.

Install Special purselock p/n:4-077-726-11 [2 places] on GTA 
board. Place side input cables (p/n:1-910-015-34) and speaker 
grill cables (p/n:1-910-015-25) in purselocks. Apply ferrite core in 
between purselocks to all cables routed in purselocks.
Ferrite core: TDK ZCAT2132-1130; p/n:1-500-386-11
Wire Routing for S-Master power Cable (p/n:1-910-015-30).
CAUTION
: Make sure cable/tubing does not sit on top of heat-
sink. Damage can occur to cable if  routed on top of heatsink
(sharp edges).

Connect CN8814(6P), CN8004(40P), and CN8400(6P) on AGA-Bd. Route
cables along stacking boss.
Dress
lighning ground cables
(p/n:1-910-015-17) in tall purselock (p/n:4-
077-726-11). Twist purselock to close it.

CAUTION
: Make sure AC cable is dressed to the LEFT of the Lightning 
Ground Wires (underneath wires). If AC cables are routed OVER the 
Lightning Ground Wires, the AC cable will push on the Lightning Ground 
Wires when the ferrite core on the AC cord is dressed in the M3 Clamp 
(on Terminal Bracket). This pressure on the Lightning Ground Wires can 
cause the terminals to bend/break and dislocate from GTA-PWB.
Dress AC Cord (above the Ferrite core) with M3 clamp 
installed on Terminal Bracket, and insert AC Grommet in slot 
on the Terminal Bracket.

CAUTION
: Make sure Clamp-on Ferrite core is
closed/locked. Make sure wires are not pinched in 
between halves of the ferrite core (main reason why
ferrite will not lock easily).
