if its obdII then you should have an obdII port to plug into under your dash, which i'm guessing you don't.  the motors are the same

The knock sensor is the wire that comes out from underneath the lower intake manifold.  The sensor itself is screwed into the block in the valley between the heads.  If/when you swap engines, replace the knock sensor.  Its like $30, and it really sucks to put the engine all the way in, and find out you're geting a knock code, when nothing is really wrong.  When you get the knock sensor, just get the one for the '95, it'll thread into the block no problem.  

IIRC, I had a couple of other wiring connections that weren't quite right, but I just cut and spliced connectors from either the donor harness, or off the components I was replacing from my truck ('91)  I also put in an '88 v6.  

this is what i would do.  or just get a 89-95 intake with the injectors and everything else on it to swap and call it good.  just my  

hurry up and get it in the truck so you can go to the round up.
