Because of how the Klima relay works, it's not as easy as just jumpering something out or swapping in a relay if you want to keep all the functions alive that the Klima performs.

If you jumper the pins in the Klima relay, the compressor will NEVER turn off, even if the high/low pressure switch opens. You also lose the WOT cutout. Depending on the year model, a jumper will have to be installed to retain use of the kickdown switch (later models had a different design). The compressor will also engage immediately when the key is turned, there will be no delay on clutch engagement to allow the engine to start.

I've thought about making a module to bypass all that Klima crap, but finding a source of pins is problematic, the issue of having some whining person claim that the module "blew up their car", and of course the common issue of the cheapskates wanting something for free, it just isn't worth the time, effort, or money to develop it into an actual marketable product. The basic schematics are posted in the thread you reference and will "get you by" with reduced functionality if someone wants to take it on.
