I was on the GM Canada Build & Price website and this was the description of the HD Trailering Special Equipment for the 2010 GMT900s:
Quote: Includes trailering hitch platform, 2.5" receiver with 2" adapter, 7-wire harness (harness includes wires for: park lamps, backup lamps, right turn, left turn, electric brake lead, battery and ground) with independent fused trailering circuits mated to a 7-way sealed connector and 4 blunt cut wires in the instrument panel harness for an after market trailer brake controller.
I have recently read here that the Colorado/Canyon trucks have a similiar setup.
Has this replaced the underdash "socket" (plug & play) that was present on the GMT800s?

Yup, you get to splice your controller harness in!

That was uncalled for!
While I have no doubt it was done from 2007 1/2 (long before the gas and bank crises) as a cost cutting measure there are actually two sides to the argument:-
Unless you bought the SPECIFIC harness for your brand of brake controller, you had to splice four connections from the provided controller harness to the plug-in harness provided by GM anyway, so what's the difference?
Future owners of the later trucks won't be scrambling looking for the GM wire harness that 90% of owners never used and threw away because it took up room in the glovebox (along with the 40A fuse for S1 in the underhood fusebox that was taped to it).
So although it sounds like a step backwards, in some ways it is not.

Pardon my french but what the %^&*!!!! Why does every thread about GM have to include this BS?
I wonder how the trucks w/ the integrated brake controller are wired? Is there a connector where the non-IBC equipped trucks have the blunt ends? I can't see the controller being hard wired to the harness.
Now I know the volumes are a lot smaller, but Bombardier snowmobiles use the same wiring harness regardless of the accessory content. Makes it a lot easier to add them later.
In the truck situation the beancounters probably figure they can save a nickel a truck by eliminating a connector on the harness. Unfortunately the assembly plants now have 2 harnesses to deal w/.
Now all I have to do is put the pigtail that Tekonsha supplied (I used their OEM harness) w/ my P3 in a place where I won't lose it before I get my 2011 truck.
Does 'ya thunk the reason GM deceided to go with a blunt cut harness and not the pigtail socket that we (GMT-800 owners) know, and love is because they already offer the IBC?
Seems kind of ridiculous to go to the expense of putting in the socket when the IBC is available, and in my estimate 99% of cases the socket wouldn't be used any way.
GM/Chevrolet has some of the brightest engineers on the planet. This is evidenced in the high quality of their products. Could it be that they know best how to build a truck? Leaving off obsolete features is a step forward, NOT a step backward IMHO.
And I agree some others in this thread, why does every GM thread have to have some waterhead chiming in with "Government Motors"?

Because it's CLEVER! Ohhhhhh! G is for Gub'mint, that's good enough for meee! Oh G is for Gub'mint, that's good enough for meeee! Oh G is for Gub'mint, that's good enough for meeeeee! Oh Gub'mint Gub'mint Gub'mint start with G!!!!
Chrysler got the same bailout, but you don't hear anybody making jokes about them. You gotta be a thinking person to "get" a joke about Chrysler's bailout, but it only someone with the mental capacity of Cookie Monster to get the "Government Motors" joke. Guess who the people that came up with the Government Motors joke are playing to?
To stay on topic, I really don't get why they didn't at least put a connector on the pigtail, instead of leaving it blunt cut... If you ever remove the brake controller, you have to cut the wires to get the original pigtail back.
It was so nice to buy a pre-wired harness for the Prodigy.
