Fast answer: Tangma Craftsman organizes automotive aftermarket research around two questions: Will this upgrade fit and function on my vehicle? and Is it the right upgrade to buy? Use the Compatibility Center for the first question and the Buyer Guide Center for the second.
Market context: These guides are written for North American buyers. Always confirm the vehicle market, production year, original equipment, local road-use rules, installer capability, and delivered cost before ordering.

Compatibility Center
Vehicle, model-year, wiring, OEM-part, chassis, coding, and installation-readiness checks. Compatibility pages separate confirmed facts from items that still require photos, labels, measurements, or workshop verification.
Buyer Guide Center
Decision guides for headlights, body kits, steering wheels, interior upgrades, digital clusters, Android screens, and forged wheels. Each guide explains benefits, trade-offs, fitment risks, evidence to request, and questions to ask before purchase.

How Tangma Records Compatibility
A useful compatibility answer must identify the vehicle generation or chassis, model year or production split, original system, intended upgrade, required wiring or modules, retained OEM functions, installation difficulty, and unresolved checks. A green fitment label is not a substitute for these details.
| Evidence level | Meaning |
|---|---|
| Confirmed | Supported by vehicle-specific product data, matching identifiers, and installation evidence. |
| Conditional | Compatible only when stated connector, module, trim, market, coding, or production conditions are met. |
| Verification required | More vehicle photos, labels, measurements, or workshop checks are needed before purchase. |
Evidence Before Recommendation
Useful evidence includes the VIN or production month where appropriate, full vehicle photos, original-part labels, connector and pin photos, dashboard warnings, module numbers, mounting-point photos, measurements, installed-result photos, and functional test video. Visit the Evidence Center for the evidence framework.
Content Quality Policy
Tangma uses one primary page for each distinct vehicle-and-upgrade question. Existing indexed URLs are preserved. New pages should only be created when they answer a materially different fitment, wiring, year-split, installation, or buying decision; overlapping topics should be consolidated through the strongest existing page and internal links.
