So Im looking at finally getting back into swapping the 307 out for the 5.3 but looking at the factory wiring what do I need to keep? The factory harness is a nightmare.

Well, that's a pretty vague-assed question...... What are you doing for gauges? Are you keeping AC? What constitutes a nighmare (worse than a carbed 5.3 in a Cutlass)? What trans are you going to run?
The basics you need to keep are the 3 heavy gauge wires to the ignition switch (red, pink, and purple) aside from the front lights and horn harness.

I think I found the answers I was looking for but I plan on keeping AC, Heat and running a 2004r in the car. I understand that there are 2 separate harnesses, one for the computer and one for the ignition, tach etc. is that correct?
No, 3 harnesses: ignition and gauges, computer, and lights and horn. 4 if you count cruise control...
I have to ask: why carb an LS?

Thats how I got the motor no intake or ECM.....Ill start off with a carb and probably go with a fitech setup later.
