You should be fine. As long as the harness and 'puter are a match you should have few issues. I know on the 90 the 'puter had a different plug arrangement than the 94 did. Granted the 90 was an auto while the 94 was stick so that may have been the deal. The harness were the same other than the plugs to the 'puter. Allt he plugs on the engine were the same if I recall correctly. Go for it mang. Have fun and dont get too discouraged. A buddy of mine just swapped the complete harness, dash cluster andsteering column into his 83 from his rolled 85 to convert his. It actually seems to be th easy way out.....
