Stereo & Electronics - Wiring harness?

Anybody know the part number for a complete wiring harness for a 98 LS1? Or the price? And I was wondering if the make a harness just for the engine and pcm, and then just get autometer gauges or something to put in the dash.

I bought mine at Walmart for under 10 bucks.

Well, I got my gauges working now so I am not that worried about it at the moment. Thanks anyway
