    I need some more specific information from those of you who know, because I can't find the specific answers I'm still looking for.

    What I'm looking to tow is a very light aluminum fishing boat on the bumper with a trailer ball. That trailer just has two tail lights on it that require the 4-pin connection (no brakes that need a controller).

    The lights on this trailer are dinky, probably 3" square red lights that blink with the turn signals and stay steady when my brake lights are on. I understand that the aftermarket harnesses simply split the brake lights at the end of the truck, and share that circuitry (which causes problems depending on how much juice you use), but my use case is really small here, and I'm not looking to tear apart my brand new 2011 just for a harness.

    Is this the correct harness for my situation:

    Or is this one:
    http://www.suspensionconnection.com/cgi-bin/suscon/7281T.html

    Or are they the same damn thing?!

    Also, can anyone point me to a TW thread that has pictures of someone installing one of these aftermarket harnesses?

    That's the right concept however neither of those say they fit a 2011. The install is very very simple. You just have to take out the tail light assembly (2 screws), then unplug the connector that goes to the brake light and turn signal. The adapter T's into this connection, essentially creating a splice, and powers the flat 4 connection for the trailer. The second one claims to fit the 2005 - 2010 Tacoma, I would guess it'd fit the 2011 but I'd find one that specifically claims that it fits first. The first one specifically says it doesn't fit a Tacoma, it's for a T100. Try someplace like Autoanything.com or even JC Whitney.

    I know if I happen to buy one that doesn't list the 11's as compatible, and it doesn't work, then I'm SOL in terms of returning the harness, but what has changed with the 11s that make those not work?

    I tow a light trailer for my mower that has the 4-pin, I just bought an adapter for like 8 bucks that plugs into the 7-pin with the 4-pin attached. Works fine, I think I bought it at Walmart

    Hmm, problem is I don't have a 7-pin, OR a 4-pin. I was looking for one of the harnesses that split the circuit that is used by the tail lights. Does Walmart sell those?

    Ahhh gotcha, was thinking you wanted to add the 4-pin next to the 7. I don't think Walmart sells those, Good Luck
