I counted 4 holes from the engine bay to the cabin (not counting the ones I cut open). 1 on each inner fender, 1 on the drivers side, and 1 on the passenger side right behind the blower motor. the rubber grommets are just massive O with a cut in them to get around the wiring. I would say go passenger side would be best, furthest away from any spinning steering shafts etc. <img src="/forums/images/graemlins/cheers.gif" alt="" />
