I would not attempt to cut holes in the wood trim. You can buy new wood from the dealer with the extra holes - there are 9 maximum above the ACC pushbutton unit, so if there's a blank space, you can buy new wood with the factory cut hole. Or, remove something unused like Shanta did. The other alternate is to yank the fader out of the center console and use that for a switch - I put a remote factory rocker switch for my Valentine-1 in that spot. 94-up 124's don't have this hole, but again, you can buy new wood with the hole. This is an especially attractive option if your existing wood is cracked or faded... cost is in the $175-$250 range each (wholesale).
