i just got a free autometer a/f gauge ...it has three wires on it red purple and black i was thinking of just hooking the black and red to my ashtray light
(will this work?) but i dont know where the purple wire goes on my p30 ecu please help i want to get this in ( i realize many of u think its a worthless lightshow but id really like to put in in and yes have searched for a while and couldnt find much helpful info).....thanks a lot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

i thought you were supposed to attach the af purple wire somewhere on your o2

but i heard that doesn't give you an accurate reading

anyways - goodluck

 

i believe black is ground, red is power, and purple connects to your o2 sensor. i have never done this myself, and i am just going off the top of my head.

 

"well, i got all my gauges installed on the pods and i hooked up the violet wire from the autometer a/f meter to d14 on my p30 ecu. "

OH MY GOD! Dude, you put the red wire to the positive accessory, negative to a common ground, purple to the white wire from your O2 sensor. You can hook the positive to your radio fuse. Make sure to NOT ground out the purple wire or it will burn up the gauge. Have fun, be careful.

wHEN YOU SAY THE O2 SENSOR ARE YOU REFERING TO THE ONE IN THE EXHAUST OR SOMEWHERE ELSE?

 

yes o2 in the exhaust...
it is recommended to run the wire into the engine bay and splice into the white wire behind the first clip, BUT... it is much more easy and just as inaccurate if you hook it up at the ecu. d14 should do it. try a search, i know the info is out there!!

i hooked mine up to my the o2 sensor before the cat because it gives you a "more accurate" reading.....that's what I was told....

 

so what do u reccomed ....me splicing into the d14 pinout or the o2 sensor??

Take it off the ECU, its easier and is going to give the same lame light show. Either way its not really accurate.

 

I would do the o2 sensor.....that's just me....

 

any other comments anyone have a pic of the d14 pinout on the p30 before i take it out tomm?
