On my o3 harness the cranksensor connector goes over the left front head down behind the p/s pump, around the frond of the pan and back the right side of the pan rail and plugs in behind the starter. Hope this is the info you were looking for.

Using that LPE converter was a BAD move. It stranded me multiple times and was extremely difficult to diagnose. It's a POS design that when it didn't work, they didn't have the knowledge to address so their answer was to refuse to help the folks that bought them. Guess what? This was all through a WELL known shop here in Houston who had multiple problems on different cars using that box. It's a POS and LPE is a POS group. The LS3 is a FANTASTIC motor, don't stain it with a kluge band aid from LPE. It was a great idea poorly executed by a now second rate group. Save yourself some headaches and swap the reluctor wheel.
