Generally, from what I've seen, the probe is placed on the #1 runner. However I read a great discussion on NABR this morning from quite a while back discussing the #2 runner as a potentially better location due to #2 running leanest. The reasoning behind was that for a number of the people who responded, the #2 piston was the first to fail and the knock sensor is located behind #2. Granted you are probably not going to see a temperature difference large enough between the two runners to cause concern so I guess you can go either way. Personally I have not decided if mine will be on the #1 or #2 runner. However if possible, I am going to follow Hill's lead (With his permission since he's the first car I saw it done on) and have the probe placed on the underside of the manifold versus the upper, visible side.
