NOTE:
1995 models use a 32-pin (C1) and a 2-pin (C2) EBCM connector. 1996 models use a 24-pin (C1) and a 8-pin (C2) EBCM connector. See Fig 1
and Fig 2
.
Wire colors and circuit numbers are identical, however terminal numbers are different. All DTC chart testing and mini-schematics, except DTC A032, A033, A034 and A035 use 1995 EBCM terminal numbers. For 1996 model terminal numbers, refer to EBCM CONNECTOR TERMINAL CROSS-REFERENCE
table. DTC A032, A033, A034 and A035 apply to 1996 models only. EBCM CONNECTOR TERMINAL CROSS-REFERENCE
