If the 124 is similar to the 126 it won't be too difficult. You'll have to 'intercept' the temperature controller signal to the blower controller as well as the push button unit signal to set the blower on max when defrost is selected. Thinking about it, you probably don't have to intercept the defrost signal since you want the max blower setting in defrost.
