Yesterday I mounted the computer in the car and started seperating the wiring harness. From what I can tell I will be using the factory starter wires, oil pressure, temp sensor and tach wiring correct? So, basically all I need to do is get the hot ignition to the computer, wire up the fuel pump which will be fed off the computer and whatever other wires absolutely needed such as the VATS module. Can I get a diagram of the wires to show exactly what goes where and what I can get rid of? I have the 3rd and fourth gen Haynes manuals but I can't make sense of it. These wires are all color coded too. Can someone who's done this point me in the right direction? Thanks,

You are not going to be able to use the manuals that you have. Search for LS1 swaps or wiring and you will get what you need. I did the LT1 swap in my car and didnt have to spend a penny on books cause everything I needed to know was here. I have motor manuals up to 98 if they are any help I can pull schematics from them. If you have any problem on the thirdgen wiring let me know, I have done 3 swaps and can tell you where almost everything goes, or can reference back to find it. Let me know.

 

check out: shbox.com
all the lt1 wiring should be there.
I also found: alldatadiy.com to be very usefull for my cars original wiring.

 

Thanks, all I need is the pin locations coming off the LT1 computer, what wire is what mainly. I've got all the third gen's wiring memorized so it won't be a problem. They cut the wires going to the dash off the harness so I'm trying to figure out what goes where. Now, can I use the stock 87 fuse box to run everything to for the motor? Thanks for all the help

 

That website answered all my questons, thanks! This should be fairly easy now after looking at the diagrams.
