GM CARS & TRUCKS
Buick Regal T-Types and Grand Nationals
In looking near the power steering reservoir you should
find two white wires with a green plug. Carefully splice the
green wire to the green plug.
2.2L/2.4L 1994 and beyond
Connect the green wire to either the white or the white with
black wire off the coil pack.
HEI Distributors
Connect the green wire to the C-terminal/wire (usually
brown), or to the TAC terminal on the distributor.
GM Dual Connector
Connect the green wire to the white wire off the connector
(usually gray) on the coil and distributor.
LT1 Engines
Connect the green wire to white or white with black stripe
wire coming off the 32-pin connector (beneath the air
cleaner) or coming off the ignition control module (ICM)
coil pack.
LS1 Engines 1997 and 1998
Connect the green wire to the white wire coming from pin
number 35 in the blue 80 pin connector (found in the engine
bay on the passenger side firewall).
LS1 Engines 1999+
In the engine bay on the passenger side firewall find the red
connector (furthest from the fenderwell) and connect into
pin number 10 which is typically a white wire. For Corvette
applications the connector is located underneath the battery
and will typically require removing the front tire and some
of the fenderwell to access the connector. The 5.3L
Silverado truck's connector is located behind the battery on
the driver's side fenderwell. Calibrate to the 4 cylinder
settings.
FORD CARS &
TRUCKS
TFI Distributors
Connect the green wire to the green wire with yellow stripe
that is on the coil. NOTE: This wire is occasionally solid
green or a green wire with a white stripe.
2.3L, 3.0L, 3.8L, and 4.0L Engines
Connect the green wire to pin number 12 on the DIS
module (typically black wire with a yellow stripe).
3.8L and 4.6L Mustangs (1996-1998)
Connect the green wire to pin number 48 (typically an
orange wire with white stripe) in the Powertrain Control
Module (PCM), a 104 wire connector found behind the
passenger side kick panel.
4.2L, 4.6L, and 5.4L F-Series Trucks (1996-1998) and
most Super Duty and vans through 1998
Connect the green wire to pin number 48 (typically a white
wire with a pink or red stripe) in the Powertrain Control
Module (PCM), a 104 wire connector found in the engine
bay on the passenger side firewall. We do not recommend
using the shift lights or tachometers with Triton V-10
applications.
Ranger Trucks
2.3L 1993-1994, connect the green wire to pin number 4
(typically a tan wire with a yellow stripe) in the Powertrain
Control Module (PCM), or connect to pin number 12
(typically a tan wire with a yellow stripe) in the Ignition
Control Module (ICM). For the 4.0L engines, use either the
PCM connection above, or connect to pin number 2
(typically a tan wire with a yellow stripe) in the ICM. For
the 3.0L engines, connect to pin number 4 (typically a white
wire with a pink stripe) in the PCM, or connect to pin B
(typically a tan wire with a yellow stripe) in the ICM. For
1995+ engine applications, connect to pin number 48
(typically a tan/brown wire with a yellow stripe) in the
PCM (found on the passenger side firewall).
CHR
YSLER CARS &
TRUCKS
Dodge Neons
Connect the green wire to the gray wire with blue stripe
coming from the Powertrain Control Module (PCM). The
PCM can be found in the engine bay on the driver's side
fenderwell between the shock tower and front grill.
SPOR
T IMPORT APPLICATIONS
Honda and Acura
For early applications, connect the green wire to the blue
wire coming from the distributor. On late model
applications, connect the green wire to the yellow wire with
the green stripe coming from the Ignition Control Module
(ICM). In some cases there may be a diagnostic plug found
in the corner of the engine bay (driver's side) wherein you
can splice the green wire into the blue wire. If this method
does not work for the late model applications you may be
able to connect the green wire to a tachometer test
connector wire (typically a connector with a blue wire)
found behind the battery in front of the air cleaner opening
on the passenger side fenderwell.
