Air/fuel Gauge (autometer)install Help!

[SS#eater]

hi i need a little help installing auto meter air fuel ratio gauge...where do i wire into?

any help would be great

i did a search......

my mate got his wired straight from the ecu, but i hve also heard ppl wiring into the 02 sensor on the dump pipe

ben...

cheers ben

i look into wiring into ecu sounds easier

Pinout 29.

Useless gauge really. I suppose its good to see if your 02 sensor is still working....thats about it.

(Yes...I have one)

i wouldnt call it a useless guage really, i have no eng warn light so its going to be my new best friend!!

On your turbo dump pipe (which leads to your exhaust) you have a sensor which detects 02. Based on this info the ECU will lean out the fuel whenever it is safe to do so (when you back off the throttlle etc etc). If the sensor isnt working properly then the ECU wont lean out the fuel when its possible so you will get crap fuel economy for one thing (200k's to a tank). This gauge can tell you if the sensor is working or not.

on the stock sensor all the gauge does is tell you if the sensor is working or not. i have 1, simply for the flashy lights. that is the whole reason i bought it. i'm like a lyre bird. attracted to flashy things. i bought it a few cars before my skyline.

as for the wire, its easiest to go off the wire straight off the sensor off the dump. i did it on the sensor side of the plug (so its a bit away from the heat. also solder the wire on (and use as little as possible), don't use joiners as there is a voltage drop across them and will give your ecu false readings. remember the sensor works in 0.1v ranges so having a voltage drop will change what the ecu reads.

Pinout 29 on the ECU is another option which I find is easier. Unless your mounting the gauge on your bonnet.

So what colour wire is it on the ECU?

It can be different per car. Mine is a copper looking wire is a clear tube/case

Got one of these for my bday, and now trying to hook it up. I fed the signal wire to the engine bay, just want to know which of the 3 wires on the o2 senser do i connect it to? i see a white/blue, copper, and brown with tracer? this is on a RB25DET.

Do a search on "oxygen sensor" or "o2 sensor" It should come up with some links on wiring ford el sensors with the nissan wiring. And the colours.

One of them is the signal wire the other two are the heater wires.
