I wouldn't take it back. Crimps corrode over time (especially,over 20 years)... I had my bumper cover repainted,and did the R&R myself. Gently removing cover,and setting it aside will give you all the access you'll require to unwrap/inspect entire harness. I spliced in an additional ground wire on the passenger side with a ring terminal to manually ground to the underbody as further insurance.
