Having trouble figuring this out... (Autometer Air/Fuel Guage Install)
I cant seem to figure out which wires i should tap into for power ground and o2 sensor. I have an s5 n/a to Tii with n/a harness so im not sure what the heck is goign on. Ideally i should tap the power, ground, and o2 from the wires closest to the ecu right. Can someone be kind enough and try to figure out which pinouts on the ecu plugs are for these three. I cant read these fsm wiring diagrams to well.
Thank you
Thank you

Sure bro. If your using the t2 s5 ECU
2c is o2 sensor
1b is power
3b is ground
First Plug : 3Y-3W-3U-3S-3Q-3O-3M-3K-3I-3G-3E-3C-3A
3Z-3X-3V-3T-3R-3P-3N-3L-3J-3H-3F-3D-3B
Middle Plug: 2O-2M-2K-2I-2G-2E-2C-2A
2P-2N-2L-2J-2H-2F-2D-2B
Last Plug: 1U-1S-1Q-1O-1M-1K-1I-1G-1E-1C-1A
1V-1T-1R- 1P-1N-1L-1J-1H-1F-1D-1B
2c is o2 sensor
1b is power
3b is ground

I got a boost guage, oil pres. guage, and air fuel guage off my friend for $60 so why the heck not? autometer phantom guages. seriously i guess that checking if your narrow band is working is the only use. Looks cool at night. Cant really think of any other reasons.

oh remember, dont cut the wire. Just shave the plastic off it and wrap your wires around the exposed wire. Use small metal clasps or better yet buy urself a solder gun and solder the connections (and of course use elec tape). Its easy to do and you can get a cheap gun at radioshack for 10 bucks. TBH i solder all my wire connections now and they are solid.

agreed the narrowe band simply seems eratic because of the ecu correcting itsself in such cshort time incraments essentialy if you are looking for a rough tune then yeah its fine but bottom line is no tuning will be even remotly usful without a dyno because a car can have 14:1 across the board but actualy that could be causing it toloose power so tuning with either a wide band or a narrow band is usless the gauges are primarly used for monitoring
