just ordered somethign had to share
just ordered somethign had to share well i had to share. i just ordered the wiring harness from eficonnections going with the coil packs and ls1 pcm on my build
im real excited i had to share. i have the coil packs already got the timing cover i needed will just have to order a pcm and the reluctors and anything else to go with it. figured id order the harness now so it'd leave time for them to put it together.

I just looked at the price for these alittle more than what I expected. But I understand the possiblilties it opens up. Could you do the same thing if you found a donor car and just ripped everything off it or are the harness connectors different for some sensors? Just tring to educate myself alittle Thanks

Verdad Gallardo Awesome shouldnt be to hard as I completly depinned my harness to strip it down to bare essentials then repinned it. I will just have to find a site like Shbox that gives all the pin outs.
i thought about spendin 100 for the do it yourself harness but i suck with wires. actually i hate wires. so i saved myself the headache and just spent the money. im happy that ill be able to get anyone to tune the car now
I use to hate wires to but I had to learn to love them working on Aircraft. On Aircraft they only use a single color for everything white could you imagine tring to trace a wiring prob. 
^^I have friends that do that ****..I would be like WTF..lol
Here are a couple I just found doing a search..

F'ing smurfbitchin F/A-18's!!!!!! I'm lucky, I got out of the Navy and haven't had to do any of that in 4 years now.
LOL Luckily I have never cause a fire although I had a friend cause one wired a DC Gen backwards pilot went to crank heard aloud pop and tons of smoke coming out the avionics compartment. I just walked away nonchalant whistling
I respectfully disagree 
The best route would be to START with a 96-97 LT1 harness and then buy the new PCM connectors from EFI connection and pin it out at the PCM. Then use the 99-02 LS1 PCM.
It's easier to pin out the PCM connectors and use the 96-97 harness than to modify alot of the connectors/wire lengths on an existing 99-02 wiring harness.
Just my opinion though

OP, welcome to the club, I spent the money for the whole shooting match (01 LSx pcm, custom harness, billet timing cover, 24x reluctor for dr timing set, LS2 coils). Because I have heard that the 15 year old factory harnesses are usually very brittle and the last damn thing I wanted to have to do is try and track down any electrical gremlins. I paid the cost to have peace of mind.
