99 ls1 into a 98 3.8 fbody Hey all I was wondering what it would take to swap my ls1 from my 99 TA into a 98 3.8 firebird donor car? The most concern I have is the wiring harness part. Would I be able to completely be able to transplant the wiring harness from my car into the 3.8 car? I know from searching around on the forum that it's most optimal to use a 98 ls1 harness but I would rather use what I have for cost effectiveness. I already know to swap the kmember, steering rack, radiator, and my fuel system or fuel pump.

I think the connections on the engine harness that would have to be changed are the MAP and ECT pig tails, then you would need to re-pin the ECM Red/Blue connectors to match up with the correct pin for the 99+ harness.
Like everyone said, it is doable.. just PITA
If you have all of the 99+ body wiring, You can also consider converting the 98 body into a 99+ one by using all of the wiring (or what is needed) from the 99+ body (BCM, Dash/Gauges, etc).

Well I already have a LS1 car, the problem is the cost of getting the bodywork, paint, and new front bumper done on mine. So I got a v6 bird that I'm probably going to be picking up for a couple grand. I'm hoping to sell the tranny off of the v6 bird, the wheels off mine, and see what a junkyard will give me for my TA. So that's why I'm considering doing this, cause I have my donor car. And the motor/tranny is already out of mine lol.

ah well that makes it cheaper I suppose, but if it were me I would fix the trans am...when it's done you have a fixed trans am
when the swap car is done you have a ls1 firebird (aka ugly IMO) with more potential for gremlins
if anything I would part out the t/a and put the couple thousand cost of the firebird with that and you might end up close to the price of another ls1 car
don't expect more than $100-200 for your car with no engine/tranny from the junkyard

Lol if you could see the poor state of my TA...there's not really much I could part off mine, considering I want to keep the whole drivetrain from engine all the way to my 9bolt rearend. I don't mind the look of the firebird, and I will take the spoiler off the TA and i got a WS9 hood that I've been hanging onto. I would prefer a TA just for the looks, not really concerned with the whole oh you just have a firebird. Yeah I just got a firebird with 450hp. Plus insurance should be cheaper...Bonus!

not trying to be a downer, I just don't know the details I guess
I just despise the look of the firebird/formula...don't care what other people think about em either, so if you like it that's cool
I just thought lots of other stuff (steering rack, brakes, ect) were **** on the v6 cars too, power isn't all of it
If you already have the stuff it could be a good deal too, I was just curious

^^Do this. Everything will of course match up. Rewiring and repinning will suck. If you're not doing anything with the 99 cluster, use it with the 99 pcm and harness, especially if the 99 cluster will fit in your 98 v6 dash (I had to use a different dash for my 93 v6 Camaro when I did my swap).
