HP Tuners offers two versions of its CORE transmission control harness distinguished by connector count, and the COR-HAR-004 is the two-connector variant for builds needing dual harness connections to the CORE ECU. At 3 ft. in length, it pairs pre-terminated leads with additional labeled open leads so the correct wiring can be matched to the transmission control strategy in use.

HP Tuners COR-HAR-004 Compatibility Notes:

• Terminates 2 connections for transmission control wiring to a CORE standalone ECU.
• Measures 3 ft. in length with labeled open leads for additional sensor and solenoid circuits.
• Suited to 4L60/4L60E and 4L80/4L80E transmission control applications.
• A single-connector version (COR-HAR-005, sold separately) is available for builds that only need one harness connection.
