Use DEI part number 555U. *1 These wires will meter when using the passenger door lock switch. *2 The ECM/PCM is on the front of the transmission tunnel. The connectors are on the passenger side. On the 4 cylinder models the tach wire is in the white 31 pin connector E, pin 25. On the 6 cylinder models it is in the gray connector A, pin 23.
