Well, it doesn't matter what side the ground is on, as I found out. Y'all, I'M STUPID!!!! I read the above directions, but somehow missed the part about disconnecting the button pods from the CRUISE CONTROL WIRING HARNESS AND LEAVING THE HARNESS IN PLACE!!!!! I bought my replacement buttons from the dealer ($58+tax), and they came with a new wiring harness already atached. I didn't even think to look and see if they were detatchable. So my dumb ass is out their in the 95 deg. heat trying to remove the old wiring, how does this thing go around....oh, I see, this wire is looped under the horn thingamabob........CRAP! The wiring harness disconnect wire is in a chistmass tree put into the BACKSIDE of the stearing wheel frame......CRAP!!! No NEDDLE NOSE PLIERS!!!! Well, let's see if we can squeeze 2 flat blade screwdrivers together......
Got it all back together, and put the battery cable to the positive post and WAAAAAAAAAAAAA. CRAP!!!!!!! The horn is screwed up. Disasemble the thing again and jiggle the wiring around until it all cleared the airbag pod.......
Finally it worked. MAN! I still can't keep it staight in my head how to start the car after the battery has been disconnected. Finding that little button to push while turning the key.......
Anyway, road test was successful.
P.S. the reason I know that it doesn't matter about which side the ground is on, is that my new wiring harness has the ground on the left....old one was on the right.
