charcoal cannister purge?  On the TBI 350 I put into my Blazer those
wires were routed under the oil pan.  Also, I seem to remember
alternator wires going under there.  I specifically remember a pair of
wires (red and blue) that went under the pan, but I can't recall exactly
what they were for, other than I didn't need them but left them in place
because I couldn't extract them from the harness.  That helps a lot,
huh?

Chris, you really need to buy the Chevy service manual for that IROC. 
It'll save you a lot of time and headaches.  I spent about 40 hours on
the wiring to put a 350 TBI motor into my S-10, with the factory manual
for the donor engine and a Chiltons for the truck.  It would have been
easier if I had the factory manual for both.
