Anyone with a 93-97 car with LS1 gone back to LT1? Help please.

Anyone with a 93-97 car with LS1 gone back to LT1? Help please.
I'm pretty sure I'm going to have a ton of people tell me this is dumb but I'm looking at an LT1 car that currently has an LS motor in it but if I get it I want to put the LT1 back in. I know that's going to sound extremely odd but that's where I want to take this car.
So my question is what needs to happen with the wiring to get it back to using an LT1 motor? I know it will need the computer and the harness those are a given but I have heard/read there is some cutting and splicing of wires done when originally going to LS. But I'm not sure what all that is and how to reverse it. Has anyone done this or am I the only dork who wants to, lol. Wouldn't surprise me if I was but I'd really like some advice. I don't want to get too deep into the wiring of the car but I really want an LT1 back in it.
Can someone shed some light on what needs to happen with the wiring aside from the harness and computer...the car has both the LS harness and computer currently. Thanks guys.

I'm really not worried about getting parts what I'm worried about is making sure all the wiring is done properly so everything works when I get the LT1 motor back in it. Like I said I remember hearing that there are some wires you have to cut/splice to get the cluster and what not to work but I guess I'm trying to decide how to reverse that and not get tangled up in an electrical nightmare.
Right now I'm only concerned with how to fix the harness inside the car not the engine wiring harness.

If i decided to go back LT1 the harness i could just unplug and plug another 96 LT1 harness and go, so hope fully they didn't **** the the car harness and just repinned the LS1 engine harness.

Don't bother trying to retrace everything he has done and splice wiring back together. Order a new LT1 wiring harness and start plugging in. If you find other harnesses that have been modified, replace them too. Look for an LT1 being parted out for that. The last thing you want is to lose the car to a fire. Start by looking for all the harnesses that plug into the LT1 ECM/PCM.

it shouldn't be as bad as you think to take it back to lt1. there are wires that need to be added to the ls1 harness for the gauges to work properly on a lt1. as stated above, you should be able to unplug and plug in a new harness from the same year as the chassis and it should be fine. the only thing to check is that the c100/c105 are still pinned exactly the same. Not hard and not time consuming.

Why? Because it's not what you would do??? I happen to like LT1's and LS1's stuff is more expensive. I just wanted to do a simple rebuild and take the car back to where it was originally. If I was building a race car then maybe I'd keep it LS but I'm not so don't need all that. Some people like having original cars. I'm sorry that's not your opinion but that doesn't make it retarded.
I've decided not to get into this car. I'd rather get one that already has the LTX stuff in it not one that's been tampered with.

Absolutely retarded. OP unless this is some special edition you want to convert back to original just find another car. And where is this expensive LS stuff? Aside from maybe LS intake manifolds the prices are no different

Launching!
LS oil pump- around $100. SBC/LT-$30
LS cam-$400 SBC/LT-$300
I'm not saying the LS is that much more expensive but to say they are the same is ignorant... A lot of the parts are the same price but some of the pieces are quite a bit different... You can buy a run of the mill LT rebuild kit for around $300, and LS kit is twice that....

So you want an "original car"? Ok, buy a super low mileage LT1 car then.
Besides that, it is just straight twisted to want to buy an already cheap F-body, want to keep it a stock LT1 when you already have a stock LS1 in there with more power, more tuning capabilities if you ever wanted it down the road, more aftermarket, better fuel economy, etc.
All of the trade offs for a better sounding car maybe?
