wiring

[b454rat]

Im looking into an LS swap for my 98 Tahoe. I got most of it figured out, what mounts to get, A/C brackets for stock compressor, headers, even turbo headers since planning on doing that. But what I can't find is the wiring that I need to KEEP off the vehicles wiring. I understand the engine side, but want everything to work, gauges, heat, A/C, cruise, stuff like that. Searched better part of the day, search results don't seem to bring much info. Not sending it out to get thinned out for a grand either....
