Match the vehicle. Match the controller.
02 / CONFIGURATION
Vehicle details
Provide market, make, model, production year and engine code. Describe engine swaps and previous wiring changes independently of the chassis.
03 / CONFIGURATION
Original ECU & connectors
Record the original ECU part number, label and connector identification. Connector-face photos and the relevant pinout can be shared in follow-up correspondence.
04 / CONFIGURATION
Target controller & existing wiring
Identify the target controller hardware revision, current harnesses and the functions you need to retain. State which parts are already installed.
05 / CONFIGURATION
Wiring scope
Distinguish universal wiring, a vehicle adapter, bypass wiring and a loose connector / terminal set. Confirm both endpoints, branches, length and termination.
06 / CONFIGURATION
Fitment review & limits
Review the pin assignments and electrical signals with the matching vehicle and ECU documents. Similar connector shapes are insufficient. A Prado engine designation or another vehicle name is a lead for the inquiry, rather than a guaranteed fitment.
Review checklist
- Cross-check connector identity, pin numbering and the drawing view at both ends.
- Record electrical signal, supply, return path and any shielding requirement from the matching manual.
- Confirm lengths, branch labels, termination and the agreed inspection record.
