Might want to look into selling the 98 computer and going with 99+. Assuming you could sell the 98 for as much or almost as much as you could buy a 99+ for it will give you a lot more options for harnesses.

Just My .02

If your set on using the 98 pcm I'd give Speartech a call.

Painless makes a computer and harness kit (Perfect Hi-RPM System) and it works flawlessly. But, I'm still waiting on them to release the software.

The harness is pre-terminated with all new wires and ridiculously easy to install. Driveability is awesome and it eliminates the MAF. I love mine.
