Hey guys I'm helping a friend, he has a whole bunch of wires cut on his F350 and since I'm doing a new harness on mine, we figured we'd just do both ours at the same time. Mine is easy enough, pre-OBDII. His is a California model, with 7.5l and RKE. Now by finding the part numbers, I have found F7TZ-14401-EA, which says "California, Gas, O/8500gvwr, WITHOUT RKE".

Also found F7TZ-14401-FA which simply says "California, gas, o/8500gvwr"

one states no RKE the other doesn't state it has WITH when all other years state that is has it if it does. Anybody know? Calling on the NumberDummy!

I can't see there being any real function difference than besides the RKE, by 11/96 they were all OBDII and MAF I would assume.
