I have a 92 prelude H23 si and im trying to connect my Air/fuel gauge but i dont no which wire on the O2 sensor to tap into for the signal, I think its the white one out of the 4 wires but im not sure. Also there is a wire that is for the dimmer...Where should i connect that wire on the car? please be specific with your details.


Thank you,

CJ

 

for my a/f gauge i installed, i connected the wire to my ecu a/f wire (white for 5thgen), then put my power wire (which is probly your 'dimmer' switch, since i assume u only have 2 wires cuz thats all u mentioned) to my headunit power wire.

 

okay that helps with the dimmer wire. byt i want to connect the wire directly to the O2 sensor under the car? does anyone know which wire it is?


Thanks for the help.

 

Just for more info twiztid00002 which white wire on the ECU is the signal? show details please.

Thanks

that gauge is just a light show, btw.

 

Im starting to feel really stupid with this. can someone please look at the link 98vtec gave me and tell me what connector it is and what number it is for the O2 sensor wire. thank you.

 

Is it connector "A" and number 6?

 

it cant be that one because i was told that the signal wire is white. please help!!

 

look at my post again

"D14"

Also dude which wire would you wiring into to dim the gauge? what color is the wire ill be wiring into. thanks.

 

if u have an aftermarket (not Honda OEM) radio/cd player with the adapter harness, use the orange illumination wire. It only gets power when parking lights/headlights are turned on

If u also need a power source to make the gauge light up, u can use the ACC wire on the same harness behind the radio.

 

so the ACC wire is on the stock radio on the harness? what color is the ACC wire? is that orange to?

 

Can i connect it to a wire that will allow me to dim the gauges to be really bright and then not bright like the dimmer button does for my dash? can i just connect it to one of thos wire on the dimmer button?

 

so can i connect my gauge to a dimmer wire and controlle how bright the gauge will be?

 

i dont see why you would want to be able to dim it but you can go to an electronics store ( radio shack ) and buy a dimmer ****

 

okay well do you know what wire i will connect the dimmer wire to? show details please.

 

anyone?

 

does your gauge have a dimmer on it?

if so, then you can just tap into your headunits power (usually has a little black box connected to the wire, or labeled "12V power supply")

if not, the you can buy a dimmer **** at radio shack or whatever and take ur dimmer wire from your gauge to it, then from the dimmer **** to the headunits power wire.

( might need a 'ground', so you get a wire and put it from the (-)negative to some metal on your car)

(also might need a 'constant power' along with the '12V power', so you just connect a wire from where it tells you on the gauge or **** to your cigarette lighter power wire
