For the ps lines and stuff, the best thing to do is go to a local junk yard or something and take it off a 91-94 240sx and just remember how it was connected and do the same to your 89-90.
As for the swap though, it's a basic replacement of your ka24e. Just take it out and replace it with the sr20det. As for the wiring you can get the wiring diagram from srswap.com if you're doing it yourself.
I just finished my 3rd sr wiring yesterday afternoon. Took me about 20 minutes.
