Re: Tbi swap build thread

Great thread! I have two quick questions, if I may:

1) I might be getting a 91 dually with a TBI 454. Is the TBI harness that is needed for a swap a stand-alone harness, or are the parts of the harness needed part of a larger harness?

2) The 85 I am getting (avatar pic) already has had a 350 TBI swapped in with donor parts from an 87. If I put the 454 TBI motor in the 85, will the existing harness suffice? I am guessing I will need to replace the ECM with the one from the 454 truck though.

Thanks in advance!
