The wire from the speed sensor conects to the combo meter then goes to the ECU.
The wire going from the speed sensor to the combo meter is blue or gray and is located at pin number 10 of plug II2 near the ECU or at pin number 13 of plug B at the combo meter.
The wire going from the speedometer in the combo meter to the ECU is gray or orange and is located at pin number 3 of plug B for the combo meter. It can also be found at junction connector J7 behind the dash. From that junction connecter it goes to pin number 17 of plug II2 and then on to the ECU.
On the AT200 the wire from the speedometer to the ECU can be located at pin number 11 of plug F for the manual trans or pin number 9 of plug C for the automatic trans.
On the ST204 the wire from the speedometer to the ECU can be located at pin number 9 of plug C.
