To understand what you're looking for, we need to clarify what you're trying to diagnose or repair. Are you:
* Trying to find a specific wire or connector related to the transmission solenoid(s) that affect torque converter clutch engagement/disengagement? These are located within the transmission itself and the wiring harness connecting to the transmission. Accessing these requires some mechanical skill and usually involves removing transmission components or at least partially dropping the transmission. A wiring diagram specific to your vehicle year and transmission is essential here.
* Diagnosing a problem with the torque converter lockup? This could be a problem with the transmission itself, the transmission control module (TCM), the engine control module (ECM), or even various sensors that provide feedback to those modules (e.g., speed sensors). Troubleshooting this requires a diagnostic scanner capable of reading transmission codes.
* Looking for a relay or fuse related to the transmission? These are typically located in the underhood fuse box or interior fuse panel. Your owner's manual will show the location and identify relevant fuses and relays.
To effectively help you, please specify the *problem* you're experiencing. For example, "My 2000 Bonneville's torque converter isn't locking up," or "I'm replacing the transmission and need to locate the wiring harness connector for the transmission solenoids." Providing this detail will allow for a much more precise and helpful answer.
