swapping an ls2 motor with a 98 t/a harness into a 94 t/a ive looked and cant find much info on the swaps into an obd1 fbody using a 98 harness, so if anyone could help out, i could use it.
1. lt1 fbody uses 43psi vs ls1 58psi fuel pressure. should i get injectors that are 42lb on 43psi or should i put an ls1 style pump in it? or is it just as easy as going to the 99+ vette fuel filter that can regulate the stock pump pressure up to 58psi?
2. being that 98 had still used analog style gauges still wont using the 98 harness be a little easier to integrate in?
3. ive already found that racetronix sells a conversion cam sensor extension so that wont be an issue and ill just extend my factory knock sensor wires to the new locations for them.
4. i cant find any thread from people using a 98 harness to swap into a 94fbody, so any help with repining would help

i have a 94 running with a 2000 harness. it's not so much about the harnesses as it is just funadementally getting the grounds right and the 12v+ and 12v switched to get the car to run. your gauges will work based on following any of the other threads on lt1 to ls1 conversion and just follow through on that. it doesn't feel like it now, but it is as straightforward as it gets once you look back on it. don't worry about the obd1 vs obd2, it just that you need to run more power wires since the 95+ had a c100 and a c105 where you could move wires around, but the 94 only has a c100.

It's a pretty easy swap..I would install a good walbro fuel pump with the regulator.
I've always used a 1999-02 Harness, 98 wouldn't be hard, just wire it right. The 94 Gauges will work fine.
