PCM Pinout

[breast69au]

i am trying to hook up two gauges into the Binnicle in my car, the two gauges i was supplied with is a Fuel/oxygen Gauge and a OIl pressure.

I am just wondering which wires off the pcm i i need to splice into to make it work???

Thanks Brett

Fuel oxygen??
Are they the vaccum gauges or something?

no its a fuel/oxygen ratio, it tells me if the car is running lean or rich, it is hooked up to the oxygen sensors on the exhaust

so i need to know the oxygen sensor on the exhuast pin off the pcm and the oil pressure sensor pin out of the pcm

Ahh ok gotcha now.
Are they genuine gauges of holden or aftermarket?

after market

Not sure about the fuel/oxygen gauge but i ran an extra sensor for my oil pressure gauge, just used an adaptor on the factory one.
Basically i'm running both together.

doesnt the original one work with after market gauges

i have got two autometer gauges cant you use the nolden senders with them???

here are the O2 sensor pins, there is nothing in the car for the oil pressure you will have to fit a seperate sender

so the pressure sensor in the car is useless for after market gauges???
