Top critical review
Overpaid for poor quality control, just like other reviewers experienced.

It's very disappointing to pay a premium for a "complete" kit that is difficult to figure out and comes with misleading instructions.
No printed instructions included in the box, you just get a box of stuff. You have to download instructions from their website. The PDF version of the wiring diagram is cut off.
To add to the confusion, extra ribbon cables are included but never mentioned anywhere. These are only terminated on one end. They're not needed but it would be nice to know that right away.
The main issue: I carved out some time this evening to install the kit in my 2006 Trailblazer. Everything went well until I started installing the T-taps. The instructions call for three yellow T-taps (heavy gauge) and two red T-taps (light gauge). The package doesn't include any red T-taps. The yellow ones won't fit the wires that need red ones.
Also, the instructions mention a yellow light-gauge wire but there are three in the harness and it doesn't indicate which to use. I guess I'll have to poke around with a multimeter?
My dashboard is disassembled, I'm missing a part, and everything is closed for the evening. Thanks, MPC.
Edit: it turns out the wiring instructions in the PDF are completely wrong. I solved it by looking up the ignition switch harness wiring diagram for my vehicle and matching up wires with the MPC harness, function to function.
Very frustrating experience.
EDIT: Having owned this for around 10 months I am downgrading from two stars to one star.
There have been five occurrences of the car not wanting to turn off when I arrive somewhere and take the key out of the ignition.
EDIT 2: 14 months later the buttons on the remotr are losing their paint. Also, accessory power often remains on after turning off the vehicle, taking the key out of the ignition, and exiting the vehicle. Normally accessory power goes off when the door opens. If I could give this zero stars, I would.
