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

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.

Looks great, enjoy!

Indeed I will update this once I add that but it probably won't be for a month or two as its bloody cold out here right now and my truck doesn't fit in my tiny garage, LOL

you could also do as I am and add a toggle switch to the diode in the mod in this thread that would allow you to have the cargo lights (including rear facing mirror leds) turn on with reverse or not via the switch. This would save you trying to find an additional power source.
