I want to plug some device, but cant recognize SPD signal on my ECU. Where is it?

 

According to my cruise control instructions, the Vehicle Speed Signal is a violet/white wire in a black plug (second from right on the xB ECU behind glove box) Pin #17 (looking at the plug, second row up, far right wire. This is a fact, because I installed it myself! (For the xA, same color wirem same pin location, but in a different connector according to instructions). Good luck.
