look at your drivers side head..see where your temp sender for the ecm is...in the same location on the pass side head (but in the back) there is a plug..i removed that plug..then its as simple as drilling the hole out and tapping it to npt...put some grease on your drill and tap and itll help catch most of the shavings ...then i stuck a shop vac over the hole to pull out any straggler shavings
