IIIRC, the '92-'94 injectors have a higher impedance than the '89-'91's, so your ecu wont be able to fire them. Other than that it should be they should be the same, but you would be better off leaving the '89 harness on it, and sending out the '89's injectors to be cleaned and balanced and used with the '93 block.


Thanks for the reply, I just checked injector part numbers for the 89 and the 93 and they both take the exact same part number. How could the impedence then be different?

Thanks,
