For those wanting to save LOTS of money but have the time, you can do your own harness. This is what I have done a couple times now.

Buy a low mile 99-04 Cable TB truck harness for $50
Buy a pack of 50 each of 18 and 20ga pcm terminals from Mouser
Buy a crimper for MAC tools for $20
Use Lt1swap.com for fuse block details and wiring diagrams $20
Cut all the pcm wires off and seperate all the individual sensor circuits
Route the wires how you like and terminate at the pcm
Cover with flexbraid from Cabletiesandmore $20

The truck wires are plenty long to route the pcm away from the engine and you end up with about $120 in it.

The wires in a truck harness are only plenty long if you’re keeping the pcm in the engine bay. I started with a truck harness on my build. I wanted to put the pcm in the car behind the glove box. From the factory the truck pcm is located on the drivers side inner fender. I removed all terminals from the pcm and routed wires to the center of the engine behind the intake. I planned on routing the harness through the trans tunnel. After gathering all the wires I realized about half of them would be too short for the location I mounted my pcm. I later modded a stock fbody harness for a friends swap and I think that harness would have worked great in my swap as well. The fbody harness is harder to find and more expensive. I'm all for using the cheap and available truck harness. All I’m saying is consider where you want to mount the pcm.

I ended up making a new harness from scratch. I work for easyperformance.com and we build a LS1/BS3 piggyback harness for speed Inc. I figured with using my truck harness and the speed Inc harness as a template building my own would be no problem. After putting at least 30 hrs into my harness I think techrods price is a steal. Granted my harness has a lot of little extras in it, but it was still a ton of work.

I have no experience with techrods products, but if I was the one spending the money I would send techrods and email and ask if they use TXL wire. If the answer is yes I would have no problem buying one at their price. If they don't use TXL I would stay away from that harness.

I used PSI the latest project and I am very happy with the quality and fit. It has all the extras other people charge for like dual fan controls, etc. I didn't like all the plastic conduit- ended up removing most of it, and the way the fuse box fit- but I am still very happy- good luck John:thumbsup:

Jeff works for Shane. Both very personable guys, and great to deal with.

I have used two so far, totally plug and play, all connectors are labeled, and he gives you a sheet to explain why you hook up the wires the way you do. Comes with a fuse box and fuel pump relay already wired in. It also has a 5 foot pigtail.

He uses all new connectors, and yes he uses TXL wire. This harness is as good as a factory harness. He uses the convoluted tubing, as most harness makers do. I peeled it off and used the Jegs brand wire loom.
