I need/want to replace the external mirrors on my spanish built D40. I can get them on E Bay but only seem to find ones with an indicator repeater in them whilst mine do not. Does anyone know if this model has the wiring for the "blinker" already in the mirror plug or am I going to have to do a bit of jiggery pokery on them. Would be a lot easier if the wiring was already there. Thanks guys/girls.
