16. GROUND WIRE
Locate the Common Ground point under the Right Door Sill. Re-
move the nut with a 10mm socket. Attach the ring terminal of
the Black Ground Wire to the Common Ground point.
NOTE: On some vehicles the common ground is located a bit
further forward. Enough ground wire is included to reach either
location.
17. FISH POWER & GROUND WIRES TO BOOT
From the rear of the vehicle, insert the Wire Fish behind the Right
Side Interior Panel until it exits near the Right Door Sill. Use the
Wire Fish to pull both the Power & Ground Wires from the door
sill area to the luggage compartment.
NOTE: Leave enough slack in the Power wire to be able to reinstall
the Thru-wall cover and the Door Sill.
18. SIGNAL WIRING HARNESS (OVERVIEW)
The signal wiring harness contains all wiring for low and high
level signals, remote volume, and remote turn on. Items are:
(1) X9331 T-harness; (2) Remote turn-on wire; (3) Subwoofer
remote volume control; (4) Left Tweeter speaker wire; (5) Right
Tweeter speaker wire; (6) Subwoofer speaker wire; (7) RCA &
Speaker wire connections to ARC Amplier; (8) Inline labels for
HIFI/HK systems
19. SIGNAL WIRING (OVERVIEW)
The factory audio signal is obtained from the X9331 connector in
the driver-side footwell, described below. The X9331 T-harness
portion of the signal wiring harness plugs into each side of the
factory connector, and sends the signal to and from the new ARC
amplier in the rear. The ‘remote volume’ branch of the harness
is routed to the center console.
20. ACCESS X9331 & X15 CONNECTORS
Locate these connectors in the left footwell, above the dead pedal.
The X9331 is behind and attached to the larger X15. Remove
both by twisting counter-clockwise ¼ turn and pulling outwards.
Separate the X9331 from the X15 by releasing the locking tabs on
the connector joining them.
