This Coolant Temperature Sensor / AAC Valve Repair Harness replaces the faulty connection on the AAC Valve of your Idle Air Control Valve or the Coolant Temperature Sensor. Z1 also sells this connector pre wired as a pigtail to splice in to your existing harness HERE

Factory connectors under the hood are often brittle and broken leading to irritating drivability problems.  To make things worse early style connections were not sealed weather tight which leads to corroded connections and poor operation.

Now you can repair your harness with our updated connector kits.  This kit uses weather tight late model genuine Sumitomo connectors (like the ones used in 1995+ harnesses).

Don't settle for inferior alternatives, use the connector that Nissan used to correct this weak point in the EFI harness.  

Kit includes:

  • Connector with clip (1)
  • Terminals (2+1 spares)
  • Wire Seals (2+1 spares)
  • Wire & seal Retainer (1)


  • 1990-1996 Nissan 300ZX (Z32)
