Ok - lets say that I have an '87 TPI - basically stock.  Can I
just swap out a PROM for the '89 TPI to eliminate the cold-start injector
on my '87??  IOW, is there a hardware(wire harness) difference
that would prevent this (other than the cold-start injector wiring) ??

thanks for any insight/advise  

(this may lead to more questions ;)  )
