Az. My Blazer with Added antennas and added my own indicator lights to the under side of the plastic frame of the mirrors, I bought the LED lights from walmart for 8 bux and used #16 twin cable, and drilled a small hole to feed the wire from inside the door/mirror to outside, then made a small hole on the under-side of the mirror to hook up the light and then fastened the kit on to the plastic mirror (under side), then feed the rest of the cable thru the wire duct where the speaker wire go's thru, then went all the way to the front Driver side indicators and T taped them, did the same for the other side but T taped in to the front passangers side indicator.
