gauge questions

[91project]

so todays i installed my gauges and i have a few questions.

for the air/fuel gauge what color wire on the 02 sensor do you connect the gauge to? my 02 is heated with 4 wires.

for the boost/vacuum (for now) what vacuum hose works best so that the gauge reads something.

for the oil pressure gauge where does the sensor that came with the gauge hook up to one the car? is it above the oil filter? what size bolt is that also.

and another random question is for the dash trim for the gauge and stereo and all how does that come out? i unscrewed the two phillips screws above gauge, one behind the lil coin drawer thing next to the cruise switch and i undid the two above the headunit. where else are the screws hidden?

I suggest picking up a Haynes Manual, it can explain the processes much better than we can...picture and everything.

have a look in the appearence section, there should be a write up on how to take off the front dash. You will have to remove the coin tray, cruise control and dimmer switches, there are fasteners behind all three.
