See if it has a updated throttle actuator. It’ll have the date made sticker on it. I think you want 2000 and newer. If not updated then most likely the looms of wires are all bare wires with insulation that turned to dust. Could slice open the outer black rubber insulation on the throttle body and check it out

Im talking about the harness that connects to the throttle and goes through the dash into the computer in the passenger floor boards. It connects near the battery too, or are you talking about the main harness?

Same stuff., check the date on the tag near the main connection by the battery. Unravel the tape in some spots. You’ll see right away if you got a problem
