These next two are pictures of the recirculation switch. The w124 and w126 switches are a bit more complicated for what I am trying to achieve. They basically activate a relay and timer in the climate control panel for recirculation mode.
My switch is made from a rear interior light switch modified to switch off power. Unfortunately the w126 or w124 button does not fit, so I gingerly added the recirculation icon to the light switch button.
Here are pictures of the new “plug and play” harness using salvaged pig tails or plugs. After shrink wrapping the harness, I transferred salvaged “no. 4” stickers to it to prevent confusion on servicing the wires later on.
