900 L4-1985cc 2.0L DOHC Turbo EFI (1985)
a.
The module mounting bracket must be adjusted to account for the different mounting position in the convertible. Bend the mounting tab that
attaches to the module so that it is perpendicular (90~) to the tab that mounts to the floor of the car.
b.
Locate the module/bracket assembly as shown in Figure 5. Using the bracket as a template, drill two 9/64 in. holes. Secure to the tunnel with
the water-proof mounting screws provided.
9.
Mount microphone bracket in the center of the seat pivot rail. Do not tighten completely at this time (Figure 6).
10.
For Convertible models it is not possible to mount the microphone to the seat pivot rail. It can be mounted instead to the vertical carpet surface in
the same general area using a shop-supplied sheet metal screw and speed nut.
11.
Cut a 1" slit in the carpeting at the base of the seat beam to route wires to module location.
12.
If an LED is mounted in the left front speaker grille proceed as follows:
a.
M85 - M88 All Models and M89 (except CV):
^
Connect the blue wire from the LED to the violet wire from the Alpine harness.
^
Connect the violet wire from the LED to the black/red wire from the Alpine harness.
b.
M89-90 Convertible: The original LED was supplied with 12 volts directly from Fuse 24 (See Service Manual Sec. 3:2, 1989-90, p. 302). This
method is incompatible with the Alpine module.
^
Remove the LH front speaker grille.
^
Unplug the violet wire from the LED in the grille and connect the short lead from the LED to ground.
^
Unplug the blue lead to the LED and connect the short lead from the LED to the violet wire which goes back to the alarm module.
Make sure that the violet wire is connected to pin 10 of the large Alpine module connector. (Pin 10 is pulsed, positive output to the
LED.)
^
Tape over the end of the long blue wire disconnected from the LED since it leads back to Fuse 24.
