[MC1.6.4/CC1.63] Bundled Cables Not Working.

ProjectRed bundled cables and Minefactory Reloaded Rednet cables aren't connecting properly to Computers. Bundled cables don't connect at all, and Rednet cables just connect via a single redstone signal.

CC 1.6 dropped all support for third-party cables, and instead introduced an API so that modders could add support themselves.

This has yet to happen, and as such, there's no way to use bundled cables with CC 1.6 through to 1.63. Given that 1.64 will move from MineCraft 1.6.x to 1.7.x (and development for most - if not all - of the mods which provide the cables are following suit), if you intend to stick with MC 1.6.x and want bundled functionality I can only recommend sticking with ComputerCraft 1.58.

This is as intended, as Bomb Bloke mentioned. Dan decided it would be easier for all involved if he would simply create an API for other developers to make their mods use, rather than creating an update to ComputerCraft each time a new mod that needs the compatibility comes out.
We're waiting on support for MFR and Project Red. ChickenBones has already said that he's working on it for Project Red, but we're not sure about MFR. Might want to check with them and make sure that they're working on it on their end if you're that interested.
