Ok so my car is an s5 1989. Car came with manual windows. So went to do a power window conversion and i know that on s4's when converting to power
windows the harness for the regulator is already in it for a nice plug and play. My s5 didnt seem to have one on both sides and dont have the right relay box for the power windows. My friend says it cant be changed but im sure theres a way to get it done. Anyone have ideas????

 

the S5 manual window cars lack the power wire in the harness, so you need to swap the whole body harness or run a new wire, plus you need the power window door harnesses

 

thanks for the info.

 

Anyone know where the extra wire goes? I'm going to run switched power (when car is on) to the doors
