You have a bunch of reading ahead of you... there is a hundred ways to do it.

Dirty Dingo ending mounts.

You can use a stock harness from the donor truck just make sure you get the underhood fuse block or go aftermarket.

You can use a throttle cable from a 99 up trk/tahoe/suburban if you are not doing drive by wire.

There are just so many different ways as far as fans, headers, fuel, intake, gauges, etc.

Get on ls1 tech and read thru the swap forum, that will help the most.
