The MagSafe 2 85Watt Power Adapter is ONLY compatible with "slim" notebooks (MacBook Air, MacBook Pro Retina) circa 2013 and newer (excluding the 2015 MacBook and 2016 MBP).. If you need an adapter for a 2009 MacBook Pro (which is a Unibody, non Retina model), you'll have to look for a Magsafe 1 adapter. Do not purchase a used one, lots of self-appointed technicians are purchasing damages adapters and swapping cables with counterfeit parts. Probably not the best thing to say on iFixit, but I'd rather have a fully original adapter.
Matt, Apple sells replacement cables with whatever plug is used in your country (even though magsafe 2 adapters-in Europe- now come with an in-line plug rather than Schuko). Schuko cables are also pretty easy to find, used, online.
If you want to fix the cable yourself, you will find that the wall-outlet end of the cable is pretty straightforward: 3 different-color wires. The Schuko plug also has three cable receptacles, just be careful which wire is Ground.
I purchased the part to replace a non working microphone.
A few notes to buyers:
1. some smaller parts (brackets, etc) must be switched over from the non-working part (i.e. antenna cable bracket)
2. no EMI foam on the top of the replacement part's antenna. That may or may not cause problems.
3. the replacement antenna connector is a VERY tight fit. Take maximum care when connecting it to avoid damage to the board.
4. last, but not least: The first part I received was defective. The microphone worked perfectly, but the antenna had SEVERE connection problems (no connection, dropped call, impossible to make or receive calls). I contacted iFixit and got a replacement. Unfortunately the replacement had the SAME EXACT problem. At that point, to exclude a mistake on my part (I am a trained Apple Technician, but you never know), I reinstalled the original part. Connection is again flawless. Returned the part and got a refund, had to contact a lawyer because iFixit is refusing compensation. Not good.
