Your rig should have a DS4 IP and the TPS is under the dash with the pedal hanging off the sucker.
There is no adjustment on this setup.

Now if the vans still had the DB2 mechanical IP and the TPS out on the pump thats a different story.

Then TPS is what is telling the ECM whats going on and the adjustment is critical.

More info please
