I've been offered an ECU from a V90 (same year, engine and transmission as mine). I have the idea of keeping it in case of future failure of the existing one.

Will it need to be programmed for my car (VIN, security system, etc)? Or will it simply plug in and run?

Thanks for any advice - is there anywhere to read up on the ins and outs of the V90 ECU?
