The "sticky" in this 3rd gen section says something about splicing the LT1 computer into the factory 3rd gen Bulkhead.So it looks like you might need both.

If your not a member of thirdgen.org, go join. They have a whole section, and literally thousands of pages on this. Im doing the swap now. Well, Im in the middle of buying parts. There are members over there who can build custom harmesses (I have one being built now, for $500, with the computer), and lines. They can answer any question you can come up with. My user name is the same over there. PM me, and I can send you in the right direction.

Good luck.

 

IF you can read and understand a wiring diagram it is cake. Other wise look into painless wiring or Howell (sp?) wiring for a harness. Either way a LT1 in a thirdgen is a blast! My next adventure is a thirdgen vert with a LSX and a T-56
