There are 2 harnesses:
PCV, Boost Gauge - P/N 25536303
EGR, Purge, Fuel - P/N 25525671
I believe (check me, I'm not 100% sure) both are discontinued.
Somebody (I can't recall, it may have been Jay's) is reproducing the PCV, Boost Gauge harness as 2, separate lines. Anyway, I saw the reproduction lines at Norwalk last year, and perhaps elsewhere.
I believe (again, check me) the small, formed PCV hose is also discontinued. However, there is (or was) an alternative hose that works perfectly with just a little, simple trimming - P/N 10055808.
