For each entry (stable, testing, unstable) you have pin-priority 500. You shouldn't use pin > 1000. I use 1001 only when I want to downgrade something. I have testing+sid+experimental entries specified in /etc/apt/sources.list and the following /etc/apt/preferences file:
Package: *
Pin: release o=Debian,a=testing
Pin-Priority: 900
Package: *
Pin: release o=Debian,a=experimental
Pin-Priority: 130
The value 500 is default for unstable. So, let's try to check iceweasel:
# apt-cache policy iceweasel
iceweasel:
Installed: (none)
Candidate: 17.0.10esr-1~deb7u1
Version table:
26.0-1 0
130 http://ftp.pl.debian.org/debian/ experimental/main amd64 Packages
24.2.0esr-1 0
500 http://ftp.pl.debian.org/debian/ sid/main amd64 Packages
17.0.10esr-1~deb7u1 0
900 http://ftp.pl.debian.org/debian/ testing/main amd64 Packages
So, if I tried to install iceweasel, it would be downloaded from the testing branch because it has the highest priority.
Try to change the priorities to:
Package: *
Pin: release a=wheezy
Pin-Priority: 900
Package: kpcli
Pin: release a=jessie
Pin-Priority: 910

Some software projects provide pre-compiled binaries for several distributions. For Debian, look for a
.debpackage. If you find one, just run:Look also: http://backports.debian.org/Instructions
