cut off the wire loom, then download the swap info doc in my sig (or go to lt1swap.com). trace the wires from the ECM, that'll be your best bet. your '99 is probably exactly like my '00. See below for my thoughts.
PCM pinouts
fuseblock pinouts
Looks like IGN 3 voltage - I did not use I don't think it's a knock sensor, due to its close proximity to the other plug.
