    I have a 2009 silverado LT and has DL8 mirrors and I would like to replace them with the DL3 mirrors with the puddle lamp and fold option. I've got the new mirrors and can already see I need the switch/control panel. Do I need to replace the passenger one also? I'm also guessing I'll need to have the computer re-flashed after replacing these 4 things so they will work. HELP

    Sir I think we are trying to accomplish the same thing. I have DL8 in my 2005 silverado and want to put in with signals..Here is the Muth mirror systems instructions... it will have instructions for the signal.

    now just have to find the power fold. I will keep looking.
    Question for ya.

    on the DL3 is there spade connectors for the heat and the signal?

    Well, all I can say is GOOD LUCK with all that crap. I mean that homemade rig up that website is recommending. I'd rather leave my mirrors alone then to put all that in my new truck. I just got a pair of DL3 mirrors for $325.00 off eBay and they are in PERFECT shape. Yes shipping included. I'm not going to change the switches on either door till I can find another good deal. I'll change the mirrors and the power mirrors will work and the puddle lamp and turn signal will also work, The only features that will remain out of operation is the fancy fold option that you must have the new switch for. I really don't care about the folding option at this time. Yes it would be cool, but I just like the turn signal and puddle lamp

    I don't know about the '14 trucks, but the '07 to '13 trucks have a Driver's Door Module inside the door's arm rest. A couple of winter's ago, someone broke my DL3 mirror and I had to buy a new one. There are colour coded connectors on this DDM, that match the colour of the plug from the mirror. I suspect the DL3 plug is a different colour than the DL8 plug. It's just plug and play.
    I suspect the '14 trucks are the same.

    I think you have to replace the door wiring harness also
