Retrofitting an air temperature sensor

[zlomjo]

My Berlingo had small clock and I have change it for Multifunction display B. I have installed radio RD3, remote controls at stearing wheel, activated trip computer. I would like to retrofit temperature sensor. In the place of outside temperature it shows me only --. So I have been informed that at connector 40V BA on the BSI I have to connect at position 8 and 18 temperature sensor. I found one temperature sensor from Lancia, connected it to BSI, but display still shows me -- . Does it is necessary do some action with Lexia?
