The Wiring node for torque reduction is where you choose which ECU output acts as the torque reduction output. You'll need it whenever another part of the system has to know that torque is being cut, or when you're building a shift-cut setup that uses a physical wire.
In most installs, a DPO (Digital Pulsed Output) is the right choice. Pick a free one and note the pin in your wiring records.
What to check
- The output you pick isn't already used by another function.
- The device on the other end expects the signal the output provides, whether that's a switch to ground or another type.
- Confirm with a test light or meter that the signal actually reaches the far end before your first shift.
