COREY

the

 

circuit

 

board

 

from

 

the

 

bottom

 

and

 

are

 

soldered

 

to

 

the

 

top.

  

Be

 

careful

 

that

 

they

 

don’t

 

short

 

together

 

as

 

there

 

are

 

small

 

traces

 

that

 

come

 

close

 

to

 

them,

 

and

 

also

 

keep

 

them

 

away

 

from

 

the

 

switch

 

contacts.

 

I

 

used

 

24AWG

 

wire.

 

Once

 

that

 

is

 

done

 

cut

 

a

 

notch

 

or

 

drill

 

a

 

hole

 

in

 

the

 

ISM

 

plastic

 

cover

 

to

 

fit

 

the

 

wires

 

through

 

when

 

snapping

 

the

 

ISM

 

back

 

together.

 

Mine

 

came

 

out

 

the

 

front

 

of

 

the

 

ISM.

 

(If

 

installed

 

in

 

the

 

car,

 

the

 

side

 

of

 

the

 

ISM

 

that

 

faces

 

the

 

front

 

of

 

the

 

car)

 

Next,

 

construct

 

the

 

circuit

 

that

 

my

 

schematic

 

depicts.

 

All

 

of

 

the

 

parts

 

are

 

available

 

at

 

Radio

 

Shack.

 

The

 

RFID

 

coil

 

can

 

be

 

made

 

from

 

any

 

coated

 

wire.

 

28AWG

 

transformer

 

wire

 

will

 

work

 

well.

 

I

 

used

 

28AWG

 

aluminum

 

wire

 

that

 

I

 

had

 

lying

 

around.

 

100

 

turns

 

will

 

work

 

fine.

 

Make

 

sure

 

that

 

the

 

tip

 

of

 

your

 

spare

 

key

 

will

 

fit

 

inside

 

the

 

coil.

 

Don’t

 

make

 

it

 

too

 

big

 

either;

 

you

 

want

 

the

 

tip

 

of

 

the

 

key

 

to

 

just

 

fit

 

inside.

 

The

 

spare

 

key

 

will

 

be

 

taped

 

or

 

tie

wrapped

 

inside

 

the

 

coil

 

and

 

the

 

coil

 

will

 

be

 

hidden

 

up

 

inside

 

the

 

dash

 

so

 

no

 

one

 

can

 

easily

 

get

 

to

 

it.

 

The

 

RS

 

(Remote

 

Starter)

 

doesn’t

 

need

 

a

 

lot

 

of

 

current

 

because

 

this

 

car

 

uses

 

a

 

low

 

current

 

digital

 

ignition

 

switch.

 

So

 

I

 

hooked

 

the

 

RS’s

 

power

 

wires

 

to

 

a

 

spare

 

fuse

 

in

 

the

 

IPEC

 

22.

 

(fuse

 

panel

 

at

 

left

 

side

 

on

 

the

 

dash)

 

I

 

removed

 

the

 

RS

 

main

 

30

 

amp

 

fuses

 

and

 

replaced

 

them

 

with

 

10

 

amp

 

ones.

 

The

 

RS

 

should

 

also

 

include

 

a

 

keyless

 

entry

 

feature.

 

Without

 

this

 

you

 

won’t

 

be

 

able

 

to

 

unlock

 

the

 

door

 

when

 

the

 

RS

 

is

 

active.

 

This

 

is

 

because

 

the

 

CIM

 

ignores

 

all

 

keyless

 

entry

 

requests

 

from

 

the

 

factory

 

transmitter

 

when

 

the

 

ignition

 

is

 

on.

 

Unfortunately

 

because

 

the

 

entire

 

car

 

runs

 

on

 

a

 

bus

 

system,

 

you

 

will

 

need

 

to

 

feed

 

wires

 

into

 

the

 

driver

 

door

 

to

 

access

 

the

 

lock/unlock

 

and

 

trunk

 

release

 

wires;

 

unless

 

of

 

course

 

you

 

can

 

find

 

an

 

aftermarket

 

I

BUS

 

interface

 

for

 

a

 

Saab

 

9

3.

 

Good

 

Luck!

 

You

 

can

 

also

 

purchase

 

a

 

RS

 

with

 

keyless

 

entry

 

and

 

an

 

alarm

 

if

 

you

 

want

 

even

 

more

 

security.

 

I

 

used

 

the

 

Avital

 

4103

 

which

 

has

 

keyless

 

entry.

 

You

 

can

 

get

 

one

 

on

 

EBAY

 

for

 

about

 

$50.

 

Use

 

the

 

WIS

 

to

 

find

 

the

 

wires

 

and

 

connectors

 

for

 

the

 

parking

 

lights,

 

door

 

locks,

 

trunk

 

release,

 

brake

 

light

 

switch,

 

hood

 

switch,

 

(if

 

you

 

have

 

a

 

factory

 

alarm)

 

etc.

 

Follow

 

the

 

instructions

 

that

 

came

 

with

 

the

 

RS

 

to

 

hook

 

up

 

these

 

wires.

 

You

 

will

 

only

 

use

 

the

 

IGN

 

#1,

 

IGN

 

#2,

 

and

 

START

 

outputs

 

on

 

the

 

RS.

 

You

 

will

 

not

 

need

 

the

 

ACC

 

output.

 

Connect

 

these

 

wires

 

to

 

your

 

newly

 

created

 

circuit

 

board.

 

Also

 

connect

 

the

 

wires

 

you

 

previously

 

soldered

 

to

 

the

 

ISM

 

circuit

 

board

 

to

 

your

 

new

 

circuit

 

board.

 

I

 

highly

 

suggest

 

using

 

plug/jack

 

connectors

 

so

 

things

 

can

 

be

 

removed

 

easily

 

for

 

testing/troubleshooting.

 

With

 

any

 

luck

 

when

 

you

 

hook

 

everything

 

up

 

it

 

will

 

work.

 

If

 

it

 

doesn’t

 

work,

 

you’ll

 

need

 

basic

 

electronic

 

troubleshooting

 

skills

 

to

 

find

 

the

 

problem.

 

I

 

have

 

it

 

working

 

on

 

a

 

2008

 

Saab

 

9

3

 

Turbo

 

X

 

with

 

the

 

B284R

 

2.8T

 

V6

 

engine

 

with

 

an

 

automatic

 

transmission.

 

I

 

didn’t

 

fake

 

the

 

module

 

wake

 

up

 

(prepare

 

to

 

start)

 

signal

 

as

 

the

 

B284R

 

engine/ECM

 

will

 

start

 

just

 

fine

 

without

 

it.

 

Other

 

engines/ECMs

 

may

 

need

 

this

 

signal.

 

It

 

is

 

used

 

primarily

 

to

 

prime

 

the

 

fuel

 

pump.

 

On

 

this

 

engine

 

the

 

fuel

 

rail

 

remains

 

under

 

pressure

 

while

 

the

 

engine

 

is

 

off

 

and

 

the

 

pump

 

can

 

almost

 

instantly

 

supply

 

the

 

required

 

pressure

 

to

 

the

 

rail

 

anyhow.

 

If

 

your

 

engine/ECM

 

needs

 

this

 

signal,

 

another

 

wire

 

will

 

be

 

required.
