    I'm looking for the actual fuse box diagram with relays (not the fuse diagram that's on the tip down storage cubby/owners manual). Have looked through countless threads and am not finding anything definitive to tell me what relays are which on the fuse panel under the dash.

    Might someone have a relay diagram for the fuse panel for a 2011, 2012, or 2013? I'm hopeful one might look the same as mine.

    Thanks much!

    Here's one for 2006. Don't know if it's exactly the same.

    20171125_201854.jpg Thank you @Muddinfun , that's the type of diagram I'm looking for, but it does not match up with mine. Attached is a pic of the relays on the fuse panel that I'm trying to identify (and subsequently track onto the actual wiring diagram, which I have).

    That pic I posted is the back side of the fusebox. (Side facing the front of the truck). There are 3 relays on the right side of the pic. The only other "relay" that I know of attached to that location is the turn signal flasher. Just FYA, the turn signal flasher is in different locations depending on if you have DTRL or not.

    Here is a pic of the 3 blue relays. The finger is pointing to the non DTRL flasher.

    Thanks again, @Muddinfun . I may be using the wrong terminology. It's the relay system location manual that contains the information I'm seeking, but is the top part of the fuse panel (facing driver). Here's an '07, but it is different than what I have in my '12. Trying to figure out which connector is which. Appreciate the help. 07 Wiring for Fuse Box.jpg

    Thanks--got it done. Tapped into the rear turn signals for Trail Ridge tow mirror LED's. Wanted to be sure I had the right wires. Once I found them and used a couple of Positaps, I'm golden and the mirrors are flashing. Appreciate the help. In case anyone needs to know, it's the blue/white wire and the yellow wire for the 2012 TRD OR coming out of the 1D wiring harness at the fuse box.

    Someone else with same model/year stated it was green not yellow, which is the common to the rears. I wanted to make sure so I didn't poke multiple unnecessary holes. Appreciate it @Muddinfun !

    Here's a photo of the wires that I tapped (behind the footfeet panel), the corresponding turn signal wiring diagram section, and the connector schematic.

    @MCM78LC Good job! Nice looking truck.

    Just don't drive around with them flipped up when you're not towing.

    Yeah, I know! I've seen the cartoon before--emblazoned in my brain. (I admit I did drive down a road less traveled just to make sure they worked well and not overly vibrated.) I've got a 16' Airstream I tow behind, and I'm sick and tired of the clamp-on ones. I had to pull the trigger.

    Thanks much for jumping in on the assist @Muddinfun !
