An LS engine swap is a no-brainer when it comes to adding some affordable horsepower to a project car, but any swap comes with its share of headaches, including wiring. That's where TSP's engine and transmission wiring harness comes in. It is designed for engines from 1997 - 2004 LS1 and LS6 Corvettes and 1999-2006 drive-by-cable GM trucks with T56 manual or non-electronic automatic transmissions.

TSP LS Harness w/T56
It’s a good reliable fast and cheap harness and it had free shipping all for 260$. You can’t beat it and it’s a must have everything came labeled as well and the MAP sensor and Reverse Lockout weren’t inter crossed with eachother (I checked with my continuity meter.) A good harness for a low price with free shipping and great distribution. In my opinion you cannot beat that.
