Default Simple LS1 harness

Not really a hybrid or conversion, but my 2004 LS1 GTO is now a drag only car, and I want to relocate the computer and fuse box from the engine bay to under the dash, and replace the large wiring loom in the engine bay with something simpler and more user friendly to install. I don't have the AC, electronic trans, cruise, ABS, etc. What is available?

Thanks

I wish I could, I am just not handy when it comes to wiring.

I went to Alldata.com and got the schematics,manual, wiring diagrams, for the 2006 GTO and labeled my own harness.... Now Speartech did my computer but the harness I did........

But if you just need a harness, painless is pretty easy for around $750.... plug and play

If it is anything like a F-body LS1.. just do the same and turn it into a stand alone harness.. strip it apart, remove any extra wire and connectors.. reposition the connectors and harness to see if it will reach into the glove box.. I move mine inside directly behind the engine. on top of the trans tunnel.

just need the correct grounds, batt 12v and switch batt 12v., Tach, VSS (if needed), fans (if used to the relay). Data port..... etc.. some extra relay and fuse.. and your done.
