2000 JGC ...Is there an elect diagram?

2000 Jeep Grand Cherokee. 104k miles. I need to do pin-to-pin continuity checks on the PCM harness ... and I'm a bit color-blind. I got a few single sheets printed out at the local dealer, but the counter person knew of no source of a complete diagram that I could buy.

Where does the full diagram reside? In the shop manual?

I have done numerous net searches that, in the end, have turned up crap of little/no relevance. Please don't send me to Ebay, or Haynes, or Chiltons ... I want the full, detailed model/year specific diagram. I'll willing to buy any manual or disc from Mopar or Chrysler ... but I never see that any particular publication includes the wiring information.

??

So to answer my own question: I have ordered and recieved the 2001 Grand Cherokee shop manual ... all 2" plus thick of it ... and it seems to have all the wiring diagrams included. So now I am dangerously endowed with information ....
