Is it supposed to have any pulse or something? i am just a little worried to not damage the ECM by doing this sort of a setup. Is it safe ?? 100% ?? :p

I don't believe that Yaris for your area have the cruise functionality. Besides that, the black wire is the horn. There are two additional wires that get added to D3 for cruise control.
