This is some of the details on the swap that I did. Some of this info will help you guys that are looking into this. I went through this thread and put every post of mine with pics and info to the beginning here so it's easier to see.

Wiring:
I researched and completely built the Harness that I have. It took about 15 hours to complete. I stripped it completely out, leaving only the essentials. I took out the AC, A.I.R., EGR, TCS, Cruise Control, Rear O2's, and a few other things. I added LS2 Fuel Injectors, and the Connector for a Corvette 85mm MAF. I also re-wired the Coolant Temp Sensor to the 3-wire Sensor and Connector from a 1998 F-body LS1(part number 12551708). The 3rd Wire is for the Gauges, they are still Analog cause the Car is older than a 1999.
I re-wired it to plug directly into the LT1 Chassis. Everything is where it should be, all the Gauges work, and the Tach has been adjusted. I re-wired everything for the T56, and even moved the O2 Sensor Connectors to above the Transmission, now I don't need any Extentions. I also moved the Grounds to the Passengers side Head, I made them to bolt to where the Oil Dip Stick Tube bolts onto the Head.
I also went through the Wiring from the Connector on the Wheel Well and going through it all the way to the Fuse Box. I re-wired the Fuse Box to clean up some things and to give each circuit in the Harness power and made it run on a fuse. I also re-did the wiring for the Cooling Fans so they run with the PCM, and I have them running on Manual Switches.
Above is a Link to a little guide on how to wire in a LS1 Harness
Here is a pic of the Engine Harness after I got done..
Fuel System:
The LT1 Fuel System is pretty much a seperate System from the PCM, so all it needed was power and it was good. I matched up all the required Wires for it, and it works, Gauges didn't have to be touched. I had to use a 1999-up LS1 Corvette Fuel Filter/Regulator to make the Fuel from the 2-Line LT1 System go into a single inlet Line to the LS2 Rails. I'm using a Walbro 255 Fuel Pump.
Mounts:
I'm using a LS1 K-member with LS1 Mounts. The Upper Mounts have Polyurethane Bushings installed. I am using the stock LT1 T56 Crossmember for the LS1 T56.
LS1 Polyurethane Mounts..
LS1 K-member installed..
I did have it mounted in with Conversion Mounts on the LT1 K-member for a while though..I had to use the LS1 setup due to Drivetrain clearance issues. The Conversion Mounts I used moved the entire Drivetrain back 3/4" to the rear, the Drive Shaft to Transmission clearance was too tight.
Steering:
The Steering had to be changed out for the LS1 Rack, it clears the Engine, the LT1 Rack and Linkage won't.
Under the car is a UMI Performance Adjustable Torque Arm. I have the one that has the Relocation Crossmember designed to bolt the Torque Arm to it instead of the Torque Arm to the Tranny..
Overall this swap isn't too difficult to do, the Wiring was the most time-consuming part cause I wasn't familiar with it, and now that is easy to do..
