Thinking of adding turning arrows inside the rear view mirrors. Unsure which ones to buy but I have a question first. After running the new wires thru the doors where is the easiest place to connect to the turn signal circuit under the dash ? Surely some one else has already done this ? Thanks. *BW*

 

Check to see if new wire really needs to be run.

 

Haven't found a good wiring diagram yet but don't think a '04 Tahoe had any other wiring to the outside mirrors other than the ones to adjust the viewing angle. Thanks. *BW*

 

Am looking for a wiring diagram for a 2004 Tahoe. I want to put turn signal arrows in my rear view mirrors. Have any of you already done this ? Thanks. *BW*
