you will need to have VATS programmed out of the PCM, I recommend having the emmissions and VSS codes removed as well, there are only like 4 different wires you need to run(you will need to hook them into the LT1 harness) 12V constant, 12V key On, ground, and a 12V key on for the O@ heaters, you should be able to tap into the original engine harness for these

I recommend running 2 more wires for the diag. connector as well, I would mount it inside, but not absolutely required
