Overview
This guide will explain the basics of installing the CAM Pro device in any Turn Key Start Car type. You need to have a proper understanding of the car’s electrical system before installation. It is highly recommended to install this device through a trained car electrician.
There are two basic car types
- Key Start – Cars that require a key to be inserted in the keyhole to start the car.
- Push Start – Cars that are equipped with a smart key remote and a push start button.
This installation guide focuses on cars with Key Start System.
Power:
Connect 1 to ground and 2 to a wire coming out of the car’s 12V battery.
Trunk:
Wire 3 should be connected to cars equipped with an electronic trunk release in a negative trigger.
Grip 2:
The Black/white wire goes to the engine starter deactivation relay. This relay is to be attached between the Starter wires of the starter wire. The remaining wires of Grip 2 are not connected in a standard installation.
Lock / Unlock Doors:
(Negative Trigger) (Standard Protocol)
The door power window module has a lock/unlock button. This button operates on -ve trigger. You need to find those wires by using a multimeter or car electric circuit tester.
To determine the wires, shift the multimeter to voltage. Connect one end of the multimeter to positive wire, and the other end to different connection points in the door module and press the lock button. The voltmeter would show a reading when the correct lock wire is determined.
Similarly, find the unlock wire with the same method of connecting the multimeter one by one to the wires and pressing the unlocking button simultaneously.
The grip 3 of the MoboKey module is for lock / unlock and indicators. Connect (10&13) (Pink) to Ground and leave (12&15) (Grey) floating.
Connect 11(Blue) to the unlocking wire. Connect 14(Blue) to the locking wire.
Make sure to check the connections by locking and unlocking it from a smartphone app.
There are two possibilities for connecting the wires.
- By opening the door trim and connecting MoboKey wires directly to the wires coming out of the power window module grip.
- By tracing these wires back to the car column below dashboard on the door side and connecting wires there instead of opening the door trim. This method is highly recommended and is easier to implement in the long run.
Indicators:
Determine the indicator wires by using a voltmeter. Turn on the right indicator and connect the multimeter, with one end at the ground and the other end to the connectors. The voltmeter will give you a reading on the correct wire. Similarly, find the correct wire for the left indicator. Connect (8 & 9) (Yellow)wires form the MoboKey unit to the right and left indicators respectively. You can also connect one yellow wire to the indicator flasher unit.
Remote Start Installation:
First, open up cover around the ignition switch. Take out wires of ACC, Power/On, and Starter. Some cars have built-in relays while others need to attach external relays.
If the internal wiring is of the similar in with to the Grip 4 wiring of the MoboKey device, then no external relays are needed. Cut the wires at the points 1,2,3 and connect them to the points 5,6,7 respectively.
If the internal wiring is thick and similar to the green wires with the relays, then don’t cut the wiring at 1,2,3,4 and connect as shown in the diagram.
If the car has a manual transmission, don’t cut the wire at point 3 in any case and make sure to connect the negative wire of the relay to the negative of the handbrake.
Security:
Cut the power wire at point 8 as shown in the diagram and connect the two red wires of engine starter deactivation relay to both sides.
Immobilizer Bypass:
If the car is equipped with immobilizer you need to bypass the immobilizer system by extracting the chip from the key and placing it near the keyhole receiver of the car in such a manner that immobilizer light doesn’t show up at the starting of the car with the device.
Some cars have similar light as above which shows the presence of the immobilizer system in the car.
