71 C-10 5.3L swap questions

[smokinstang70]

I am starting my first LSX swap... I have a 71 c-10 that I am putting a 2006 5.3L (DBW) motor and 4L60E tans in. I have all the brackets, adapters, etc etc... but I still need help on the harness. I would like to mod the factory harness as I don't have the money for a standalone.

First few questions are...

1. do I need any of the 4 O2 sensors? I was going to remove all the wiring as I plan on it being non-emissions when I reprogram the PCM.

2. Does anyone have a list of wires that can be removed?

3. I am going with a Vintage Air AC system... do I need to keep the a/c wiring in my harness or will the new Vintage Air harness take care of everything that is needed?

4. Any additional advice... lessons learned... etc will be greatly appreciated!!!

Thanks again.
