J= 1988 model year
Big engine difference between 1987 and 1988
87 is CFI
88 is SEFI

sorry... I thought that the fabrication date "11/87" and the model are the same.

I appreciate you clarify then

something that rolls off the production line that late in the year is 1 model year newer.. for example, 1 year later in 11/88, the MN-12 birds/cougars were in production, which is the 89 model year

Actually the '88 is EFI it's batch fire, not a sequential system...

Although it won't be correct by any means, I'd think it would at least start on the '87 ECM... I know someone whose ECM burned up(literally) in a '93 F-150 Lightning, to be able move the truck a 6cyl ECM was tried and it did run...

Anyone have any pin outs for the 87 and 88 ecu's? As long as the tps and igniton wires are right it should start on staring fluid. I could see it not firing the injectors long enough to keep it running.
