What kind of information do I need to give him when ordering?

Bringing this thread back from the depths, anyone has experience with them and their products?

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.
