Hi friend actually my ak12 got in an accident last month. The boot and rear bumper crashed. When garage replace the boot it was one with rear wiper but mine had no wiper. Means no control no wiring. Can someone please tell me how to connect the rear wiper or if you havd a wiring diagram or whatever. Please note that i have no rear wiper control in my control arm near steering. And what abour the rear water sprayer?
