You have to drop the tail end of the exhaust system. Since it is on rubber hangers this is easy to do. Once down, then the rear shield should be removed. Once it is removed, you can then see the cables and you just pull and unclip them.
The cables from Ford cost me 41 dollars each. O'relly sells them for around 14.00 - found this out after i bought one ford cable. You can't mix and match. Either get two ford cables or two o'reilly cables. The oreilly cables are a bit shorter and you need to reuse the white plastic bushing. The ford cable has the bushing as well as rub insulator where the cables touch the body - O'relly do not.
