Turbo watch installation

Hello everyone is my first post and first of all I wanted to introduce myself and congratulate you all for this useful page.
I have an Opel Corsa OPC and I want to install an electric tube clock from the Stri-Racing brand. The problem is that the instructions are in English, and even using the translator I do not find out. Someone has it in Spanish or has it installed in your car and can tell me how to install it.
I already tried to put it but I only marked depression, the Seensor placed it in the gasoline pressure valve. It is well placed or has to go elsewhere.
Thank you very much in advance.

Hello, if you want to mark the pressure that blows the turbo you have to put it between the turbo and the admission after the intercoler. A greeting.

Thank you very much for answering, tomorrow I try to connect it as you tell me.
