Stav,I hear your the person to talk to about wiring up the emanage ultimate, I've been labelling the wires before I install and was wondering about the knock sensor wires. On the wiring diagrams it shows knock signal 1/water temp as the same wire but it goes to 2 different locations on the Ecu location chart,is this optional , I.e knock signal OR water temp. If you know what I mean. Cheers
