2.1.4 V900093 Tach Wire (CKP signal)
□
For 2007 Classic: Find the white wire with the black stripe in the
top ECM connector (Figure 2.1). You can verify that you have
the correct wire by checking for a constant 3 Volts with the
engine idling at about 600 RPM. If your multi-meter can measure
frequency, the reading will equal engine rpm.
□
For 2006 Models: If there is a white wire with a black stripe in
the top ECM connector (Figure 2.1), ensure that it is the correct
wire by using the same verification process as for the 2007
Classic. Mark it with a piece of tape and turn the engine off.
If there is no white wire with a black stripe, find the three wires
that are dark blue with a white stripe in the top connector. Use
the same verification process as for the 2007 Classic to locate
the correct wire. Mark it with a piece of tape and turn the engine
off.
