you want a steering column with both wipers & headlights on it,try a sunny.you'd probably have to get the steering box as well,but someone mentioned recently these have a quicker ratio.also,for intermittent wipers on the sunny column,try n12 pulsar,where you can get intermittent & variable intermittent wipers,all you need to do is get the control box from the donor car,& this is right next to the wiper motor.wiring it up can be done with the help of an auto electrician.i've had this in my sunny panel van for so long i've forgotten how the wiring goes.
