Check this out, My MIL light from the PCM is Dk Brown where it goes through connector C100. On the 98's it says it's not used in C100. Trust me there are some major harness differences between the years. A friend of mine took his 96 V6 out and put in a vortec 350 and the wiring ate his lunch from the differences.

Yea, the '98s the MIL runs in through the connector on the passenger side. Definately sounds like some big differences
