Need help to install these. I have a 00 Si. Anyone have pictures or wiring diagram of where to tap off for the PGM wire O2 sensor? And where does this Oil Pressure gauge sensor plug into? Any help would be apprecitated. Thanks.

 

is the oil press gauge elec or mech? if its mech, the tubing runs from the stock oil pressure sender through the firewall to the back of gauge. if its elec, the tube runs from stock oil pressure sender to gauge sender. make sure sender is grounded via mounting or use a wire. would recommend mounting sender on firewall or any other location other than the block itself. wire runs from sender to back of gauge where the "s" is. ground at back of gauge where it has a "g", and the last one is 12v.

might wanna figure out where u want to mount the gauges before you hook em up. good luck

 

Thanks man. Anyone else have details or pictures for the AFR gauge?
