And I got the 4WD working in the '95. I had a couple of extra 4wd switches and they didn't do anything. I've been working on different things and simply didn't get around to messing with it.
I briefly looked at the fuse box in the '95 and it was missing the relay in spot #12. Of course that control electronic 4WD among other things. Swapped in the relay from the '93 EB and the truck switches in and out of 4WD with no problem. Engage 4LOW as well (of course in Neutral) but doesn't make a rather loud clunk only when engaging 4LO - and no weird noises with it locked in a driving around the yard.
