今まで使っていたSD カードを 新しいRaspberry Pi B+ で動かすのはできたのですが、WiringPiを実行してみると26ピン分の表示しか出ません。

元々このSDカードに入っている WiringPi は、git clone してインストールしていました。
そのときのディレクトリがそのまま残っているので、以下のようにして最新のコードを引っ張ってきます。
pi@raspberrypi:~$ cd wiringPi pi@raspberrypi:~/wiringPi$ git pull origin remote: Counting objects: 20, done. remote: Compressing objects: 100% (20/20), done. remote: Total 20 (delta 18), reused 0 (delta 0) Unpacking objects: 100% (20/20), done.

あとは ./build だけでインストールできます。

NOTE: To compile programs with wiringPi, you need to add:
-lwiringPi
to your compile line(s) To use the Gertboard, MaxDetect, etc.
code (the devLib), you need to also add:
-lwiringPiDev
to your compile line(s).

では、うまく動くでしょうか。

おや、だいぶ雰囲気が変わっています。この新しいバージョンを、従来の Raspberry Pi B で動かすとどうなるでしょうか。

旧 Raspberry Pi でも新しい表示形式が使われるようです。
