how to install motor temperature meter

I want to install a meter to an Opel Zafira in 2007, which does not bring it from the factory. Just bring the sneak when there is an emergency. I am fearful that the boarding computer became crazy when I put the car in the car.
Tarch has installed it and can advise me from the steps to follow.

It is not complicated, there are two views and a mechanic, they are only a name, do not worry, you should search the engine to make a couplet in the water circuit to be able to mount it, let it be in contact with the water as much Independent of the Orijinal installation, you will have no problem.

First thank you for constant kikemec. Then I bought the meter told me that I was in the motor block in a screw of this. And as I indicated above I do not know that tension cables take not to bother the switchboard. And I do not understand what you want to say with (the installation is completely independent of the Orijinal installation).

If they told you that in the block there is a screw draws that screw, see that you effectively have water and put the Ally score, with respect to the tension cables you mention will depend on which voltage worked the marker that you bought if it is with 12 volts, it combines you to remove a cable from battery directly, or in its defect Throwing it to chassis is recommended, the independent installation refers to the fact that you put cables and do not click the cables that the vehicle brings, anyway as long as you do not click any sensor you will not have problems.
