I have No buttons next to the shifter, but i was looking under and found this, can I hook this up and make it functional to whatever it goes to? Are there more harnesses underneath (I didn't look all that closely)?

i think thats for the CCR controll....

For when you have the Struts that you can select the rid style...

Traction on/off, Performance shift off/on, CCR ride control. All Bonnevilles have the harness regardless of whether or not they have the options installed.

Ah, that'* exactly what I wanted to know, thanks! Now if I hook the buttons work, will the traction and perform shift actually work?

Not if your car didn't come optioned with that equipment.

You found that under the blank plate right?

The shift thing should still work.

yes

The PCM is not programmed for the shift mode. It will not work.

if i hook the traction control button up, will the traction off light get falsely turned on since there is no traction control?
