Re: 4.0 info

A: I moved the knock sensor ahead to where one of the XJ motor mount bolts 
used to be. I just threaded the hole to fit and put a 12mm bolt in the FSJ 
bracket (same place Eagle and AMC car bolt on) where the knock sensor used 
to be. Now I'm putting HO EFI in my '84 J10 and it's another whole ball of 
wax (whacks?) trying to figure out the Grand Cherokee wiring!

i thought the hole was tapped for the knock sensor - unused - even on
ho blocks, for compatibility reasons.

the eagle diff mount boss is there somewhere.
