The place to tap into for oil pressure is the same on all engines...the pressure sender....need a T there.....and for afr you would never tap into a o2 wire...each wideband gauge is calibrated for the lambda vs voltage scale...so your gauge may not match the sensor.....you always mount an extra bung holio in your exhaust pipe for your new wideband gauge...a wideband gauge will always come with an 02 sensor
