Warning! Safety first The following safety warnings must be observed at all times: • Due to the complexity of this system, installation of this product must only be performed by an authorized Ungo dealer. • When properly installed, this system can start the vehicle via a command signal from the remote control. Therefore, never operate the system in an area that does not have adequate ventilation. The following precautions are the sole responsibility of the user; however, authorized Ungo

After the remote start module has been installed, test the remote start mod- ule in accordance with the Safety Check outlined in this installation guide. If the vehicle starts when performing the Neutral Safety Shutdown Circuit test, the remote start unit has not been properly installed. The remote start mod- ule must be removed or properly reinstalled so that the vehicle does not start in gear. All installations must be performed by an authorized Ungo dealer.

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 volt

➤ 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 dis

Finding the wires you need Important: Do not use a 12V test light or logic probe (com- puter 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

How to find the starter wire with your multimeter: 1. Set to DCV or DC voltage (12V or 20V is fine). 2. Attach the (-) probe of the meter to chassis ground. 3. Probe the wire you suspect of being the starter wire. The steering column 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 connec tions is always rec ommend ed. 4. Turn the

➤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 availa ble to the starter motor. How to find (+)12V ignition with your multimeter: 1. Set to DCV or DC voltage (12V or 20V is fine). 2. Attach the (-)

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 dif- ficulty 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: 1. Set to DCV or DC voltage (12

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 sens- ing. 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

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 igni- tion 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 conne
