I am in the process of retrofitting a roller blind from a 500e into my '89 300e and have sourced all of the components with the exception of the wire harness. My question is how is the rollerblind linked to the headrests?

From information gathered from previous posts - the rear headrests will not drop if the rollerblind is not fully seated. According to the EPC the same wiring harness is listed for both the 124.030 and 124.036 ( p/n 124 540 31 13). Where are these 2 components linked? Was there a different style of roller blind used? What year was the split?
