Thats one big red truck, no missing that in the parking lot Looks good I like it with the older style wheels.

See post 4 by 15HDriver. There is a temp sensor in the passenger side mirror on diesel applications only.

The above is correct, its a bit tricky to do, I used a dental pick as I had to remove the rear seat head rest in my double cab for my son's car seat to fit.

Wow that truck looks awesome, great job on the wheels and tires!

Just like mine...only longer! Great looking truck! But of course I could be biased

Finally got my new mirrors installed, it looks so much better! Now all the other trucks don't make fun of its tiny mirrors

I believe the GM terminology for a PI is Preliminary Information...

That is interesting that you find the beams to be set a bit high as part of the service bulletin was to ensure the headlights are correctly aimed, may want to check with your service people on what they actually did.

Here is the wording of the TSB for applicable build dates: For vehicles built before 12/23/14 at Flint Assembly (11th Vin Digit "F"), 1/13/15 at Silao Assembly (11th Vin Digit "G") or 1/16/15 at Ft. Wayne Assembly (11th Vin Digit "Z"), reprogram the BCM with the latest calibration available in TIS2WEB starting on 1/12/2015. The new BCM calibration will increase the voltage to the headlight bulbs in both the low beam and high beam selections. Important: All vehicles built after the above dates already have the new BCM calibrations and the BCM reprogramming does NOT need to be performed.

Check out the K2XX 1500 forum, lots of info there on HID conversions.

Agree, I don't think its readily available online. I found it thru ESI (Electronic Service Information)......

The TSB says right in it labour times to use for vehicles under warranty. (assuming you are still in warranty period)

Thanks for noticing my typo, I updated my original post.

I'd check out PIT5374 , released Feb 27, from what I've heard it includes new bulbs and a BCM update as well as checking headlight alignment.
