Fayas with velocimeter

Hello friends, I can give you something, I have a goal of 97 Multipunto engine, I don't work for the accounting and the digital below, check the little worm that goes in the box and that's fine, change the box sensor for the box for a new one and you don't work, you can tell me if you carry any relay or fuse because I really do not understand how the circuit of the account is Kilometrso less in speed, and then I leave at all to work, thank you very much

Look at the big problem of the Volkswagen is the board is electric and you can always check it with a Scaner or take it out and send it to try it.
