How do I hook up the oil line to my oil pressure gauge? I have a 4th gen. Also, how can I hook up my A/F to my ECU? Where is the ECU exactly and what is involved? Thanks LMK in detail if possible.

ECU is under the carpet in the passenger foot rest, should be 1 white wire you can splice into to source your O2 reading for the A/F. you can use the spare spade on your fuse box as an intermitent power source

oil pressure sender needs to be hooked up to a port right under the intake cam on the left side of the engine (facing the car). you'll probably need an adapter, it doesnt fit quite right...

You can also use a 'T' fitting on the stock oil psi sensor if you have a mech gauge. It on the back side of the motor, below the filter.
