01 / GUIDE
A controller is one part of the setup
A model name or a photo does not define a complete installation kit. One listing may describe a controller alone while another describes a different package. Ask for an itemized quote for the exact configuration you want.
02 / GUIDE
Use three clear lists
Keep the supplied package separate from additional requirements. This makes omissions and duplicate purchases easier to spot.
- Included: each supplied physical part and quantity.
- Required separately: wiring, sensors, connectors or interfaces needed for this installation but outside the package.
- Optional: additions that serve a particular use rather than being necessary for every installation.
03 / GUIDE
Check what “harness” means
A connector and terminal set is not the same as a terminated harness. A universal flying-lead harness is not the same as a vehicle-specific adapter. Confirm the ends, pinout, length, branches and terminal contents.
04 / GUIDE
Include the tuning connection
Ask which cable, driver, software and computer system are required. Confirm whether software is supplied as physical media, a valid download or a separate arrangement.
Checklist & example
- Included: controller ×1, with the exact connector / harness contents listed.
- Required separately: installation-specific sensors, wiring termination or tuning interface if outside the package.
- Optional: monitoring or mounting additions checked for the project. This is a neutral checklist, not a sellable kit.
