Several instances of alternate wire colors going to the C(3)I module on 1989 Century and Skylark vehicles equipped with a 3300 (VIN N) engine have been reported. This would effect wire colors on diagnostic Charts A-3, C-4H-1, C-4H-2, and Code 42 Chart found in Section 6E "Driveability and Emissions" of the Service Manual. It would also affect the wire colors on the ECM Wiring Diagrams at the front of Section 6E3-A "Driveability and Emissions" and Section 8A "Electrical Diagnosis".
On vehicles that have the alternate wire colors, the circuits remain the same. If the colors do not match that of the Service Manual, they may be as follows:
