Installation points to remember
This product is designed for fuel-injected, automatic transmission vehicles only.
Installing it in a standard transmission vehicle is dangerous and is contrary to
its intended use.
➤ Intelli-Tach
Intelli-Tach is a new feature for Ungo this year. It is the default RPM-sensing
method for the new remote start system.
Intelli-Tach gives the installer the performance of a hard wired tach wire, with
the convenience of voltage sensing. It is far superior to any voltage-sense feature
you’ve tried before.
Intelli-Tach monitors the cranking voltage of the vehicle using a very fast micro
controller and an analog-to-digital converter. The microprocessor “saves” the
base voltage as a reference. When Intelli-Tach “sees” the slightest uptick in
voltage, indicating that the alternator is charging the battery, the starter motor
shuts off instantly.
➤ D2D
The system has the ability to interface with an XK module through the D2D port.
The advantage to using a D2D interface is that there is less wiring involved in
the installation. Check the XK module installation guide to determine which wires
are not needed, and which options are available.

➤ Before beginning the installation
Please read this entire installation guide before beginning the installation. •
The installation of this remote start system requires interfacing with many of
the vehicle’s systems. Many new vehicles use low-voltage or multiplexed
systems that can be damaged by low resistance testing devices, such as
test lights and logic probes (computer safe test lights). Test all circuits with a
high quality digital multi-meter before making connections.
Do not disconnect the battery if the vehicle has an anti-theft-coded radio. •
If equipped with an air bag, avoid disconnecting the battery if possible.
Many airbag systems display a diagnostic code through the warning lights
after the lights lose power. Disconnecting the battery causes the anti-theft
code to be erased, which can then require a trip to the dealer.
If using an external LED or Program Switch, check with the customer about •
where to locate the switch.
To avoid accidental battery drainage; turn off the interior lights or remove •
the dome light fuse.
Roll down a window to avoid being locked out of the car.•
➤ After the installation
Test all functions. The Using Your System section of the Owner’s Guide is •
very helpful when testing.
Review and complete the Safety Check section of this guide prior to the •
vehicle reassembly.

Finding the wires you need
Important: Do not use a 12V test light or logic probe (computer safe test light) to locate these wires. All testing described
in this manual assumes the use of a digital multimeter.
➤ Obtaining constant 12V
We recommend two possible sources for 12V constant: The (+) terminal of
the battery, or the constant 12V supply to the ignition switch. Always install a
fuse within 12 inches of this connection. If the fuse will also be powering other
circuits, such as door locks, a power window module, or a Nite-Lite® headlight
control system, fuse accordingly.
Important: Do not remove the fuse holder on the red wire. It ensures that the control module has its own fuse, of the proper value,
regardless of how many accessories are added to the main power
feed. .
➤ Starter wire
The starter wire provides 12V directly to the starter or to a relay controlling
starter. In some vehicles, it is necessary to power a cold start circuit. A cold
start circuit will test exactly like a starter circuit, but it does not control the
starter. Instead, the cold start circuit is used to prime the fuel injection system for
starting when the vehicle is cold.

How to find the starter wire with your multimeter:
Set to DCV or DC voltage (12V or 20V is fine). 1.
Attach the (-) probe of the meter to chassis ground.2.
Probe the wire you suspect of being the starter wire. The steering column 3.
is an ex cel lent place to find this wire. Re mem ber you do not need to inter-
rupt the starter, unless an optional anit-grind/starter disable relay is going
to be installed. Hiding your starter kill relay and con nec tions is always
rec om mend ed.
Turn the ignition key switch to the start position. Make sure the car is not in 4.
gear! If your meter reads (+)12V, go to the next step. If it doesn’t, probe
another wire.
If installing an optional anti-grind/starter disable relay, cut the wire you 5.
suspect of being the starter wire.
Attempt to start the car. If the starter engages, reconnect it and go back to 6.
Step 3. If the starter does not turn over, you have the right wire.
Connect the key side of the starter wire to terminal 87a of the optional 7.
relay.
Connect the violet wire along with the start motor side of the wire to termi-8.
nal 30 on the relay.
Connect a wire from the 12V switched ignition wire to terminal 86 on 9.
the relay. (See "finding the 12V switched ignition wire" for assistance in
locating the wire)
Connect the orange wire (H1/5) from the 9-pin harness to terminal 85 10.
of the relay.

➤12V switched ignition wire
The ignition wire is powered when the key is in the run or start position. This is
because the ignition wire powers the ignition system (spark plugs, coil) as well
as the fuel delivery system (fuel pump, fuel injection computer). Accessory wires
lose power when the key is in the start position to make more current avail able to
the starter motor.
How to find (+)12V ignition with your multimeter:
Set to DCV or DC voltage (12V or 20V is fine).1.
Attach the (-) probe of the meter to chassis ground.2.
Probe the wire you suspect of being the ignition wire. The steering column 3.
harness or ig ni tion switch harness is an excellent place to find this wire.
Turn the ignition key switch to the run position. If your meter reads (+)12V, 4.
go to the next step. If it does not read (+)12V, probe another wire.
Now turn the key to the start po si tion. The meter display should stay steady, 5.
not drop ping by more than a few tenths of a volt. If it drops close to or all
the way to zero, go back to Step 3. If it stays steady at (+)12V, you have
found an ig ni tion wire.
➤ Accessory wire
An accessory wire will show (+)12V when the key is in the accessory and run
positions. It will not show (+)12V during the cranking cycle. There will often be
more than one accessory wire in the ignition harness. The correct accessory
wire will power the vehicle's climate control system. Some vehicles may have
separate wires for the blower motor and the air conditioning compressor. In
such cases, it will be necessary to add a relay to power the second accessory
wire.
➤ (+) Parking light wire
Most vehicles use a (+) parking light circuit. The (+) parking light wire is often
found near the light switch. In many vehicles the light switch is built into the turn
signal lever; in these vehicles the parking light wire can be found in the steering column. The same wire can often be accessed in the kick panel or running
board.
13

Note: Many Toyotas and other Asian vehicles, send a (-) signal from the switch
to a relay. The relay then sends (+)12V to the bulbs. Whenever you have difficulty finding a (+) parking light wire near the switch, simply test the wires at any
switch or control panel that is lit by the instrument panel lighting. Remember, you
need a (+) parking light wire that does not vary with the dimmer setting.
How to find a (+) parking light flash wire with your multimeter:
Set to DCV or DC voltage (12V or 20V is fine).1.
Attach the (-) probe of the meter to chassis ground.2.
Probe the wire you suspect of being the parking light wire. Usually, the 3.
area near the headlight/park ing light switch is an excellent area to start,
as is the kick panel.
Turn on the parking lights. If your meter shows (+)12V, turn off the parking 4.
lights and make sure it goes back to zero.
If it does return to zero, turn the parking lights back on and, using the 5.
dash light dim mer con trol, turn the brightness of the dash lights up and
down. If the meter changes more than a volt when using the dimmer, look
for an oth er wire. If it stays relatively close to (+)12V, you have found your
parking light wire
Note: Vehicles that use a (-) signal from the switch to the factory relay may be
interfaced directly. (See H1/5 WHITE wire of Primary Harness (H1) Wire Connection Guide section.)
➤ Tachometer wire
To test for a tachometer wire, a multimeter capable of testing AC voltage must
14

be used. The tachometer wire will show between 1V and 6V AC. In multi-coil
ignition systems, the system can learn individual coil wires. Individual coil wires
in a multi-coil ignition system will register lower amounts of AC voltage. Also, if
necessary, the system can use a fuel injector control wire for engine speed sensing. Common locations for a tachometer wire are the ignition coil itself, the back
of the gauges, engine computers, and automatic transmission computers.
Important! Do not test tachometer wires using a test light or logic probe. The
vehicle will be damaged.
How to find a tachometer wire with your multimeter:1.
Set to ACV or AC voltage (12V or 20V is fine).2.
Attach the (-) probe of the meter to chassis ground.3.
Start and run the vehicle. 4.
Probe the wire you suspect of being the tachometer wire with the red probe 5.
of the meter.
If this is the correct wire the meter will read between 1V and 6V.6.

Making your wiring connections
Before making your connections, plan how your wires will be routed through
the vehicle. For instance, the red 12V constant input and the remote start ignition wires are often routed together to the ignition switch harness. In order to
keep the wiring neat and make it harder to find, you may wish to wrap these
wires together in electrical tape or conceal them in tubing similar to what the
manufacturer used.
There are two acceptable ways of making a wire connection - solder con nections and crimp connectors. When properly performed, either type of connection
is reliable and trouble-free. Regardless of whether you solder your connections
or you use mechanical type crimp-on connections, ensure that all connections
are mechanically sound and that they are insulated, especially when connecting
data lines in the vehicle.
Cheap electrical tape, especially when poorly applied, is not a reliable insulator. It often falls off in hot weather. Use good quality electrical tape or heat
shrink.
Never twist-and-tape the wires together without soldering.•
Never use “fuse taps”, as they can damage fuse box terminals.•
If you use tapping connectors such as T-Taps (not to be confused with ScotchLocks), avoid using them in higher-current applications (constant 12V, ground,
etc.) These connectors are inferior in quality and should be avoided.
