Dash Harness Questions

[90Tank]

Hi I'm new here. I have a 1990 V2500 Suburban that was given to me by a friend after her ex husband lit the interior on fire. I am rebuilding it and would like to know what year model dash harnesses I can use because 1990 Suburbans are kind of rare around here. Also there is a wire that runs from the dash harness to a sensor on the transfer case. Is this the speed sensor?

you are correct. the suv's & crew cabs stayed w/ the old body while the pickups changed to the gmt400 chassis in 1988. the crew cabs & suv's changed to the gmt400 chassis for the 1992 model year.
