That took under 20 minutes since I already had the connectors, a wire stripper crimp tool, and electrical tape ready. ! time job, though. I know it was under twenty minutes because I had a pork loin in the stove and when I started there was about 20 minutes left on the timer. I finished just in time to walk into the kitchen as the timer was going off. Mmmm.....new injectors and pork. Anyhow, courtesy nissan says my lower insulators should be in Tuesday. Oh happy day.
