tbi swap q.

[TxSparky]

First off I tried to search but my phone does not like the search function. I'm sure this topic has been beat to death but I simply can't get the function to work.. Q. I am going to swap my 91 tbi intake/throttle body onto and 88 block. Will my wire harness match everything? I trashed my engine so i found a cheap donor while I rebuild mine. Am I in for an electrical surprise? I might be able to get a 89 harness and ecm. I read somewhere that 91 was different from the pre 91 harness. Thanx in advance.
