Can you ID these 98 Tracker parts?

[Dewmore]

After having took all the advice given I am in a bit of better situation, due to cold and other more important things the tracker sit. Radio problem was solved by a cassette gizmo that created a bluetooth path, works excellent, ebay, , volumn seems big enough to cover road noise. The black box hanging to modulate a/c, rhe weather has not been warm enough to get a good performance review. With the warnings of Fixkick on the "Yellow Wires" I will not mess under dash, no matter how bad speedometer cable growls.
O2 sensor problem forthcoming with original and replacement having different wire colors, after market parts
