I have a 2000 silvy motor & trans. I don't know if your trans would work b/c of the year model. I think there's something with the spline count that's different on the input shaft. Not sure if that would matter if you kept your stock converter, but check to see if that'll bolt to the 4.8's flywheel. I can't answer that for ya.

As for the wiring... PM me your email, and I'll send ya the files I have for that series. If there's something you need, I'll do my best to find. I can't imagine anything's different b/t the '00 & '01 models. Maybe someone else has access to '01 stuff for comparison purposes. For what it's worth... I'd STRONGLY consider a harness from Allen (or others). I know budget may be an issue b/c that's what I said. There were times where I cuss'd & fuss'd (and still are) with the frustration of getting the wiring just right. For me, there's still one bug that I just can't say for sure that it's in the wiring. Take your time, but for a few hundred dollars (don't quote me, but it's not as expensive as Painless or Speartech), Allen can take care of your needs, and add an efan harness for a little more.
