aftermarket gauge question

[Bigcheck1]

anybody know where the oil pressure sending unit is on the engine. i have an oil pressure gauge from auto meter to hook up and my book is at home so right now i'm at a loss for where the sensort is that i have to replace.
also, does anybody have any experience with water temp sensor locations ( also have the water temp gauge to install as well.
lastly, anybody know which lead to tap into on the o2 sensor to get the air fuel gauge to work as well, there are 3 leads to the 02 sensor plug and i just need to figure out which is which.

thanks

can i just take the old sending unit off the engine and hook up the auto meter? or will this cause my computer to go screwy at all?
i dont care if the gauge on the dash reads 0 since i'll have the auto meter present

Don't know the answer to most of your questions, however I think if you remove the existing sender you will get a constant Check Oil Light, and may cause the Check Engine light to be on also. You will probably have to have a "T" connector for both or find a new location.

The same goes for the temp sensor and the o2 sensor or lots of CELs and poor running.

i got a t fitting for the oil today, gonna install all of them after my exam in the morning tomorrow. i figured out i migt need a t for the temp too. i'll figure it out. the hardest part i think is gonna be hooking to the o2 senso, i have to find the wire for the 1 volt lead, its a pain to get to at the plug by the coil pack, so iam gonna try to find it near the computer so i cna get it easier... alec, if you read this where did you get your wire at in the engine?
