67' vs 68' Service Manual - Electrical for Dart

Would anybody know if the electrical diagrams would be the same for 67' as for a 68' Dart? I got caught on 67' vs 68' c-body wiring diagrams. Wiring was different at the bulkhead connector. Just wondering if same issue here. I can find 67' Dodge Manual (contains Dart) and 68' Plymouth (Valiant) manuals on MyMopar.com however no 68' Dart Manual. Thanks.
