MOUNTING RECOMMENDATIONS
CONNECTING WIRES
Wires should be fastened to stable wires or other non-moving parts. Any heat emitting and/or moving objects should be kept away from the wires.
There should be no exposed wires. If factory isolation was removed while connecting wires, the isolation material should be applied.
If the wires are placed in the exterior or in places where they can be damaged or exposed to heat, humidity, dirt, etc., additional isolation should be applied and the wires should not be loose.
Wires cannot be connected to the board computers or control units.
CONNECTING POWER SOURCE
Be sure that after the car computer goes to sleep mode, power might be still available on the power wires. Depending on car, this may happen in 5 to 30 minutes period.
When module is connected, measure voltage again to make sure it did not decrease.
It is recommended to connect to the main power cable in the fuse box.
3 A, 125 V external fuse shall be used.
CONNECTING GROUND WIRE
Ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.
If the wire is fixed with the bolt, the loop must be connected to the end of the wire.
For better contact scrub paint from the spot where loop is going to be connected.
