Yes, those are the buttons that came in the kit. I picked up a project board from the local RS and cut it down to fit. It is secured with hot glue to the inside of the trim piece. I know how you feel, waited 30 days for mine
I am getting the calibration down, took a drive down to Cadillac today and tweaked the VSS setting. Looks like I am within about .2 miles between the tripmeter and the MPGuino after 100 miles. MPG's still suck due to the weather tho.
Here's pics:
Topside of the trim piece. The hardest part was locating the 1/8" holes accurately. I had to use a 1/2" dia. drill on the botton side to create a recess for the body of the switches, as the buttons were not high enough to stick through the thick plastic far enough.
Bottom of the trim piece over steering wheel area. Hot glued project board with buttons to it.
Quick and dirty case made from cardboard, covered with vinyl and wide electrical tape. Price was right.
