I'm not new to the z but new to the ls motors in a z, would like to thank everyone on hybridz.org I would never have gotten my L28 turbo running with out you. I just picked up a 2004 ls6 engine I took the whole wiring harness including fuse box with positive and negative cables my question is can I just hook up the positive and negative cables still hooked up to the fuse box to make it run, I know I have to remove vats ?
