I ordered the harness kit for my 93 N/A 2+2 from courtesy Nissan, and they sent old style connecors. The square ones. So I had to call and point out that 93 N/A 2+2 has new style injectors, with oblong connectors (with orange inserts).
So the guy made sure that I checked my car, and I confirmed that the connectors were the new style. He generated an RMA for me, and UPS picked it up. I paid the $10 difference. The new style harnesses arrived, and they have 4 connectors per side!
