Got my skidplates delivered Saturday and swung by O'Reillys on my way home from work today and picked up 8 bolts.

Got home, pulled it up on ramps, grabbed my cordless drill, 15mm socket, creeper, and removed one of the factory bolts from the bottom of the front splash shield. Used it along with my drill to make quick work of tapping the 8 holes. Installed the skidplates using the cordless drill/driver also.

Easy peasy, except that the snow we got here over the weekend is kinda melting and the bottom of the vehicle was wet and dripping on me.... Lol

Cut a groove down one side of a bolt and have your own self tapers anytime.... haha

Can one of you guys snap a photo of the lid on your center console without the rubber placemat. Trying to see if the bolt pattern matches up to this center console charger im trying to get. Im out of town for a few days so i cant look at mine.

Replaced my Onstar roof antenna with a two-wire version that has the built-in diplexer. So last year I did the Onstar module upgrade mod to a 2011 box so my 2009 could utilize the remote start via Onstar app feature
The older Onstar box uses two wires (cellular radio, GPS). The new Onstar box only has a single antenna connection. The problem is that you will not have GPS signal as the older style roof antenna doesn’t combine the cellular and gps signal into one wire that goes to the Onstar module.
So the old fix for this was to buy the $25 diplexer module BUT that item is long out of production and the eBayers want $100+ for it. So apparently if you just buy a roof antenna from a 2011 or newer it has the diplexer built into the roof antenna assembly. So I pulled down the headliner enough so I could stuff my M18 power ratchet to remove the 10mm bolt. I carefully pulled apart the tri-connector and extracted the individual connectors. As you see in the photo, the blue wire goes to the thick coaxial cable (cellular-GPS) and the yellow wire is for the XM radio. You can figure out which wire is what on the vehicle side wiring by turning in your good time radio set to XM and it will work when it’s plugged in properly. I just plugged them into each other and secured with electrical tape so they don’t pull out. The third wire is not necessary and I taped it out of the way.
New GM antenna part #20791465 I paid $16 for it.

My weekend so far. I said I would post more pictures of the process so here it is.

As you can see the roller stopped for some reason. it didn't spin as far as I know.
