I ve seen the process on gnttype but as always its for and 86-87 GN so instead of it being passenger side its on hte back side. but i cant tell exactly where its at or what to hook up to. kinda cramped backe there. Any help is greatly appreciated. also the fuel filter change. How to safley bleed pressure from fuel line so i dont make hurt or messy. thanks guys.

Easy way to bleed fuel pressure off is to start the car and then go to the back between the fuel tank and the bumper and unplug the fuel pump wiring harness OR pull the fuse under the dash while the car is running...The car will eventually die, you can even help it along by giving it a little gas...
After that, you won't have much pressure at all in the system...

TPS is located on the FRONT side of the throttle body (opposite of the throttle cable). There are 3 wires directly on top of it. The center (middle) wire is the signal wire. Put the positive lead of the meter to this wire (straight down into the connector should work), and put the negative lead of the meter to a good ground. Shoot for about .42 or .43 volts at idle. At wide open throttle, voltage should be at least 4.55 (obviously test WOT setting with engine not running 
).
