Description
The HKS TT-3 Turbo Timer Harness provides the listed electrical connection for a compatible control system. Application: 1991–1992 Toyota Supra / 1991–1995 Toyota MR2 Turbo / Toyota Celica All-Trac.
Design and operation
Harness compatibility depends on connector pinout and the intended control unit, not simply connector appearance. A matching vehicle name does not establish interchangeability between different electronics generations.
