I'm not famliar with the specific wiring scheme in the W126 but assuming the W126 is the same as a W124 I don't understand how you could install in "ice-cube" relay in place of the KLIMA realy. The KLIMA relay has 10-12 pins and the standard ice-cube relay has 4 pins. |
Tim, the ice cube relay eliminates all of the superflous controls that are not required to run the a/c. You lose the speed monitoring capability for the serpentine belt and the coolant temperature cutout and the kickdown cutout, but the system will work just fine, if the CCU is providing the proper ground signal.
You can install the ice cube on the W124 as well. It's been done before and works fine.
