Ok, so I am starting to accumulate parts...found an LQ4 complete, but I wanna use an LS1 ecu...I am thinking its just a maf and map change, and I should be good to go, anyone have any idea on other sensors could be different?

I would be real curious to see if anyone has a picture of a grafted harness. I am wondering how it looks when it is done versus a custom harness like this one...
92 6.0 harness
I wish I could see some photo's of them in the truck and done. I know with stuff like this, it is easy to turn a nice swap in to something pretty nasty with wires running every which way.
97SS383, there isn't really that much to an "Grafted" harness. If it's in an older car there really isn't anything except the PCM harness. The only connections needing to be made for the PCM to function on it's own are: MIL (even optional ), BATT constant, IGN switched start & run, GRounds, and that's it. When you try to intigrate it into an existing computer controlled vehicle with abs and other controls is where it gets messy. If you want some pics of my harness in the truck up close let me know and I'll get them for you. Here is a finished shot of it. There wasn't any grafting to be done on mine much .... the truck harness is basically seperate from the PCM except for about 10 or less wires, MIL, idot lights, ect...
Where in FL are you located??
Now that looks nice. Did you use the electronic throttle on it as well? It looks like you have the TAC box on the fire wall.
I also see you just yanked the entire fuse and relay center from the donor truck and used it, looks awesome.
I guess I am just curious about how it looks from someone who actually grafts the harnesses together via mail order, and how satisfied peopplke are with them. I have read several posts on forums where people say that they got a good product, but I have never seen finished pictures aside from the one you posted.
I am down near Tampa. Current Performance (the link above) is around here and I have looked at them since they are near by, but he won't graft harnesses together, he makes them from scratch for the swap. A bit more expensive, but no splices, less down time if you are trying to gather ALL of the parts you can ahead of time, and if you sell the old engine, you have the harness to go with it.
This is a thread copy from LS1Tech and I'm sure it will help explain to answer your questions. Here is the complete link for more answers. You might have to be a member to read it. Good Luck!

Wow, someone actually quoted me!! I guess I needed to put a disclaimer in my original post.

I was wondering if you'd catch on!

I've got a pic of my grafted harness before install and after . I've still gotta put them in to my computer but I'll post it later this week . My engine compartment is still kind of in a state of disarray . I think I'm going to have to disconnect the harness now that I know how it goes and reroute it so it lays differently . It's a bit twisty here and there . But , as soon as I had it installed it started right up .I had mine done at LT1350.com in Pennsyvania for $575 which included return shipping .
97 SS 383 ... Yes I went with the electronic throttle which is stock on the 04's. In my opinion I think the fly by wire is the way to go. I know I've heard several people say it sucks. It was way easy to get the cruise and throttle hooked up. I'm going to use it on my next swap.
Ok...here comes a question "the mounts have to be used upside down in the V6 swap" can someone explain this a little better? also do I have to cut the V6 drive shaft like I do in the V8 swap?
