Where does the oil pressure gauge connect to?

 

A plug in the back of your block. You have to remove the oil level sensor and replace it with the sender.

 

Where is the oil level sensor located? And what is the sender?

Anyone know where I can go to find out how to install it?

 

What wideband do you guys recommend? which one do you guys have?

 

Extremepsi.com sells some good widebands for a decent price, I would try to stay away from aem becuase it dosent read low enough for the 4g63(or so I have been told). On the 420a the oil press sensor is on the back of the block above the lower motor mount, for your car check your haynes manual that you got before you decided to do anything to your car.

 

the cheapest one to buy AEM UEGO that is what I have bought it from tearstone for $250 a while back. It is a 6 in 1 guage meaning you can change it from white face to black face with silver or black outter ring and you can read either A\F ratio or Lamda(which I am not to sure of)

 

Is it easy to install, or should I have a pro do it for me?

By the way, is this all I need or do I need something else with this?

EMonz did it himself... im sure he will give you soem tips and pointers maybe even instructions...

 

that is all you need, that is what I have. It is easy to install if you have an extra o2 bung in your downpipe if not you will need to have a hole drilled in it and a bung welded in

Here it is in my EVO

 

That looks awesome Emonz, but I dont have that extra o2 bung in my downpipe. Where did you get that done? So do I have to have this done in order to put in the wideband?
