| Installation of Z31 Voice Alert System into Z32 There are two kinds of people in the world: those who loved
the voice alert system on the older Z’s, and those that hated
it. “Bitchin’ Betty”, as it was affectionately called, appeared
in most Z31 and Maxima models, from 1984 through 1986, and
spoke five warnings:
• Lights on
• Left door open
• Right door open
• Parking brake on
• Fuel level low. Here are the installation steps for a 1995 Z32: 1. Remove Betty from the donor car with the associated
connector and at least six inches of wire. Betty is located
above and behind the ECU in the passenger kick panel, behind
the insulation. She is just slightly larger than a pack of
cigarettes, 3.5 inches (85mm) by 4.25 inches (105mm). She
is the metal box next to the speaker, shown in the test setup
below.  2. Test Betty. From the Figure 1 below, identify the wires for
ground, speaker, Lights On, and driver’s door. Connect the
ground wire to the negative terminal of your car battery.
Connect the speaker wires to a test speaker. Connect the
positive terminal of the battery to the Lights On wire. Then
by grounding the driver’s door wire to the negative battery
terminal, you should hear the Lights On warning.
3. Disconnect the battery negative cable.
4. Remove the plastic pieces from around the steering column
by removing the six screws underneath. Also remove the
upholstered piece under the steering column.
7. Remove both door sills and the driver’s side kick panel.
8. Remove the panels behind the seats. In a 2+2, you
must remove the panels that expose the wiring of the door
switches.
9. Remove the console pieces to expose the
emergency brake, and remove the package tray to expose
the fuel gauge wiring.
10. Locate the voice warning system box on the cubby
lid of console while doing the wiring. This allows you to get
the wiring to the approximate correct lengths.
11. Electrical connections. To tap into the wires, use
crimp tee connectors or solder the connections and cover
with electrical tape or shrink tubing. 16 AWG wire would be a
good choice for the electrical connections as it is much
heavier than the wiring on Betty, and easier to handle. The
tap connectors for 18-22 AWG will work with the heavier 16
AWG wire, if you use pliers to push the metal connector down
on the wires. You may also wrap this connection with
electrical tape just to make sure. Route all wires so they will
be hidden when everything is back in place, of course.
12. Mount a speaker in a convenient location such as
behind the driver’s seat. A five inch, four ohm speaker was
used in this installation. You may chose to place it in a test
location while wiring, before you locate it permanently.
13. Remove the light switch pod by removing the two
screws under it. You may also want to remove the
upholstered panel under the steering wheel for ease of routing
wires.
14. Lights on. To activate this warning these conditions
must be met:: i. The key must be removed from the ignition.
ii. The driver’s door needs to be open.
iii. The headlights or parking lights must be on. a. Identify the red/blue wire at the ignition switch.
This wire carries 12 volts only when the key is in the ignition.
Tap this wire and connect to the blue wire with red bands,
labeled Ignition Key on Betty’s connector. See Figure 1 for
connector wire layout. See Figure 2 for Ignition Switch. b. Tap the green/red wire from the light pod, Figure 3,
and connect to the red/green wire on Betty’s connector,
labeled “Lights On” in Figure 1.
c. Tap the non-black wire coming from the driver’s
door switch, and connect it to Betty’s wire labeled Driver’s
Door in Figure 1.
d. Connect the speaker wires from Betty to the
speaker. e. Ground the black wire from Betty by crimping a ring
terminal on the wire, and attaching it under the one of the
screws attached to the car body. Reconnect
the battery, turn on the lights, take key out of ignition, and
open the driver’s door…you should now hear Betty saying:
Lights On!
15. Fuel Level Low. Tap the thin blue wire coming from
the fuel gage under the package tray, and connect to the
fuel wire on Betty.
16. Left Door Open/Right Door Open. Near the right
front headlight, locate the alternator harness connector (A3
for AT cars, and A4 for MT cars) that contains the blue speed
sensor wire, Figure 4. It is the only connector in this location
with a blue wire (at least on 95 Z’s). Unhook this connector
to make tapping the wire easier. Tap the blue wire, and
connect to the speed sensor wire on Betty. You may run the
connection wire along the driver’s side of the engine, across
the back of the engine, and into the passenger compartment
through the hole under the clutch master cylinder that is used
for the hood release mechanism. If you want your installation
to look like OEM, cover the wire with black wire cover tubing.
Secure this wire/tubing with tie wraps. Also tap the non-
black wire from the passenger door switch, and connect it to
the passenger door wire on Betty.
17. Parking Brake On. Tap the wire coming from the
emergency brake switch, and connect to the Betty wire
labeled Parking Brake.
18. Tape Betty’s radio wires individually, as they are not
used. 19. Permanently install Betty by attaching her
behind/between the seats under the waterfall piece, Figure 5.
20. Replace all interior panels removed.
21. Reconnect the negative battery cable. 22. Listen to Betty. Figure 6. 23. Have a beer. 24. By the way, if you are a real geek…you can find the
connectors under the kick panels that contain most of the
needed wires. However, the connectors have many, thin
wires, making tapping much more difficult. But if you insist…
check out the electrical section of the service manual. 25. Credits. I received a lot of the basic information in
this write-up from Twinturbo.net member, Shift For Brains,
which is what I felt like after trying to decipher the wiring
diagrams in the service manual. 26. Enjoy your talking car. From Zeeway, January, 2007
