Main and engine harness swap between two cars

[allmine104]

I'm swapping the main and engine harness between a 92 awd laser and a 93 gsx do you think I'll encounter any problems like different connectors or pinouts being different? I'm trying to revive a very clean gsx that had the engine harness ,dash and main body harness stolen main harness was cut at tha floor below the drivers fuse box I'm good with solder and heat shrink... but I have a parts car that has good dash and harness that I've already removed dash and harnesses but tryn to put it back in the other car and am tryn to see if I'm gonna have any problems
Thanks

I'm hopin just a year difference won't be a problem...this is my first Dsm build I came from hondas

With a 90 the harness is different.

I anit gonna lie...I'm not lookin forward to soldering the rear/floor harness back together. I made sure when I removed the main harness from the donor car I left alotta extra wire for me to work with..any idea where I can get a factory etm for both cars to compare? I also wanna remove some unneeded circuits from the harness any ideas?
