Bill let me know I'd have to modify the 99 harness for the map and bcs. First I have to get the motor/trans out to change gaskets. Plus I think the sc is leaking from the seal on the snout.

If they plug an OBD2 connector to read the car, then you want the vin to match. PCM would need to be updated.

the perf shift button you have to add a wire to the pcm and run a button off it. or take the knob from the 98 and wire it up. take the pcm wire from the pcm plug in the t boned car.
And the BCS plug and now the wire for the perf shift. Anyone read what I write?

dont run it on the 99 pcm, the timing is way to high. and the trans wont be happy at all.
It'll run off the 98. Can't pass a plugged in test though based on incorrect vin. Trans tables will be wrong, as will the fueling and timing and cylinder airmass and a bunch of other things.

It'll start on the 99.. but I wouldn't do anything beyond a test start on that pcm.
