I'm installing a keyless entry system in an early w126. It requires an aftermarket actuator be put in the driver's door to lock/unlock the lock.
This shouldn't be difficult. Plenty of people have done this before, including people on this forum. But I've been sitting there staring at the door for over an hour now trying to figure out where to fit this $(*#^ actuator.
Those of you who've done this, where did you put it??
