Conversions & Hybrids - Source for wiring harness?????????

Where could I get a wiring harness for this build on a 6.0 LQ4 block?

Requirements:
Drive by wire, 24X reluctor wheel, L76 intake/injectors

Would a vette (drive by wire) LS1 harness/computer work?
Or would the GM LS2 plug and play setup work if reluctor wheels were swapped? How do you change a reluctor wheel?

I would think Speartech or Current Performance who both make complete kits for the LS2 engines would be able to do what you need.
The 24x reluctor I wouldn't think is a problem, you can run the older style LS1 computer and TAC module for the ETC, or just run an LS2 computer made for the 24x reluctor. The '05 Vette, '05-'06 GTO, and a few other vehicles had LS2 engines with 24x reluctors in them, so don't think that part is such a big deal.
