Designed for MY 2001…2009 (BMW ideology). Plug & Play. Manages bus wakeup, key presence monitoring and key turn enable according to EWS status.
12-pin connector: plugs directly into original connector, pin1 is marked on opposite side of board. Wire to 1st pin is usually BLUE in original car wiring loom.
Emulator is reusable (not locked to car).
HINT – if key turns, but there is no start allowed: find wire directly coming from EWS to ESL (P/N signal, wired through ESL) and short it to +12v. Or recode EWS to ignore this wire (on most cars it is ignored by default).
