So just a little background info: I got a killer deal on a wrecked 2002 Trans Am LS1/T56 car with only 39k miles. The owner put the car on its roof and was lucky to walk away from the wreck with minor injuries. He was the original owner too. My car was originally a 93 v6 car that I converted to a 1997 z28 by stripping mine to a shell and swapping everything over from the donor car. Now I will be just swapping my car instead of changing all of the harnesses and everything.
We start out with my donor car which I picked up for a cool $2500. I've been working on parting it out to make back some cash and its almost paid for itself!
Sitting in the wreckers yard the day I got it:
All stock! Just got her home, you can see the carnage somewhat.
Factory Hurst shifter
Got it all stripped out to nothing
Preparing the motor to be removed
Dropping it out!
She's on the floor

And where we stand today with my car:
At this point I'm in the process of removing the LT1/4l60e out of my car and prepping it for the swap. Once the LT1 is dropped I can modify my tunnel for the shifter hole as well as put the master cylinder in the firewall. I will also be installing Texas Speed 1-7/8" longtube headers before it goes in! And I'm trying to beat a hard deadline of next friday :icon_slap: so stay tuned because its gonna get intense!
So right now I am working on getting all of the wiring done. So far the only actual wiring that I did was swapping the front and rear 02 signal wires so that I didn't have to use O2 extensions with my long tubes.
Here is what wiring I have conceptualized after looking at harness diagrams:
This is my first time doing any major harness wiring so feel free to point out any errors or changes that might be present.
I will designate which connector the wire moves from and then to, and free spot means that the pin is blank on the connector.
Move LS1 C101 - Pin C (AIR pump relay control) to LS1 C100 - Pin E
--This will match the air pump wires up to 97 LT1 body, but I deleted the pump
Move LS1 C100 - Pin E (TP Sensor Signal) to LS1 C105 - Pin C (free spot)
--This will match the TP Signal to the LT1 TCS throttle position [is this correct?]
Move LS1 C101 - Pin K (Ignition Retard Signal) to LS1 C105 - Pin A
-- This will match LT1 C105 TCS system spark retard, I deleted TCS though
Move LS1 C105 - Pin G (Engine Speed Signal)[extend] to LS1 C230 - Pin D (free spot)
--This will match to LT1 C230 tach signal to cluster
Move LS1 C220 - Pin A (Oil Pressure Indicator) to LS1 C220 - Pin B [remove grey wire CPP switch that is in B, it is not needed]
--This will match the LT1 oil pressure feed to the cluster
Move LS1 C101 - Pin D (Primary Fuel Pump Relay Control) to LS1 C220 - Pin J
--This will match up to the LT1 Fuel pump relay control
Move LS1 C101 - Pin B (Ignition 1 Voltage) to LS1 C100 - Pin F (free spot)
--This will take power from the LT1 actuators fuse #2 [15amp] and supply power to the ignition
This is what I have so far, I will update as i figure out more wiring. Hopefully everything is correct so far
Updating with some pictures, she's coming along! I got the fuel system done and the wire reinstalled to the starter from the battery in the trunk. I converted the return system to a single -6 AN line from the stock fuel filter location using a vette filter/regulator. I got the Pontiac column in as well since my wheel was really old and bad looking, so I figured I would swap them. Plus I'll be able to have two sets of keys for my car now
Nice progress so far. The wiring isn't too bad. You just have to have a lot of patience and study all the pin outs and diagrams. I actually repinned my harness in my bedroom. lol

Oh I have been studying lol, I was drawing out the repinning when I was idle at work. I think I have a good grip on it, the only thing is that I'm not 100% sure is needed once I have some stuff depinned and just hanging out there.
Any chance one of you guys could repin harnesses for others for $? I'm at a total loss with my 97 swap, I thought the PCM could be repinned or something, I'm in the early stages still....
