Plug and Play (Plug and Play (WAMS Definition))

Concepts

A WAMS replacement module that ships pre-programmed to the customer's VIN, requiring no dealer trip and no scan tool to install.

“Plug and Play” is the term WAMS uses for replacement modules that ship pre-programmed and ready to install without any further programming, dealer visit, scan tool, or Techline session by the customer. The customer removes the old module, installs the WAMS replacement, reconnects the connectors, and the vehicle functions as if the module had been installed at the factory.

What “Plug and Play” means at WAMS:

  • The module ships as factory-new OEM GM hardware in original GM packaging — not refurbished, not salvage
  • It is VIN-programmed before shipping with the correct software, RPO configuration, and feature set for the customer’s specific vehicle
  • It is bench-tested at WAMS after programming, before it leaves
  • It requires no dealer Techline session for installation
  • It carries the full GM parts warranty on the module itself

For Global A vehicles, Plug and Play is straightforward — the module ships fully programmed and the customer installs it directly. For Global B vehicles where GM’s Techline Connect requires the module to physically be in the vehicle for the marriage step, WAMS coordinates a WAMS2U remote programming session to complete the marriage after install. This preserves the no-dealer-visit benefit.

What “Plug and Play” does not mean:

  • It does not mean a module from a third party with no programming
  • It does not mean a generic universal replacement
  • It does not mean a module pulled from another vehicle and resold

Aftermarket and salvage-yard modules sold as “plug and play” by other sellers frequently arrive Theft-Locked, with wrong feature configurations, or with no programming at all. WAMS Plug and Play means the module behaves as if the factory installed it.

Vehicle Applicability

All WAMS replacement modules across Global A and Global B platforms.

Also known as: Plug and Play, Plug-and-Play, Pre-Programmed
