The intermittent rear requires a module and an extra wire, which the Yaris doesn't have. I picked up the module from a Prius, but it needs feedback from the rear wiper motor, which the Yaris's wiper motor doesn't provide.

I built my own module which includes a potentiometer to allow for fully adjustable rear intermittent. I use timing, to replace the feedback signal on mine. I haven't had a chance to package it and install it on my car yet, but on the bench it works perfectly. I will probably mount the knob for adjusting the intermittent delay to the steering column, by the stalk.
