This is from RRE:
"1G Throttle Body
Must be from a June '90 thru 94 car ('91-94 model year). The correct one has 4 vacuum connections on the top of the TB facing towards the passenger side of the car. The earlier '89-May'90 TB has two fittings on the top and two on the front side, this one will not work. You will re-use your 2G Throttle Position
Sensor (TPS). The 1G TPS has only three wires while the 2G has four. The Idle Speed Controller
is the same between the cars."
Check out there site for the Vfaq on the throttle body install. I'm planning on doing the same as you Larryd.
