aight i have a 90 gt that im finishing up, and i need a little help

i have a set of 94/95 02 sensors, can i use them in my 1990 gt

installing an air/fuel gauge, which wire at the computer do i hook it up to

i have a 347 , afr 185, aeromotive a1000 fuel system, whats the best fuel pressure to start at

not sure on the 02's, just buy the right ones for your car, like 3 wire or 4 wire. The air/fuel usually ties into the wires on the o2's........39 to 40 on the fuel pressure...........hotwheels of turborides

well i was just wondering abou tthe 02's cuz i got a brand new set of ford ones for free, i will probably just end up getting the right ones then, about the air/fuel, reading the manual it says to attach at at the computer and not onto the o2 sensor, i was just trying to figure out which wire at the computer is the signal wire, thanks

It won't work because your eec won't recognize it.

The reason they suggest hooking the air/fuel gauge up at the computer is because the signal wire is shielded. The shield and the wire separate at the computer, and you need to hook up to the wire inside the shield. If the shield and the signal wire contact each other, it will stop the signal from reaching the EEC.

Not sure which wire, I can look it up when I get home.

Narrow-band air/fuel ratio gauges are just a cute light show...but I enjoy it!

k, i did some research, although my air/fuel gauge connected to my o2 sensor, i have found your wiring numbers for ya. According to my research, your o2 sensor wires are as follow's: #29 on your ecu is the wire that gets the info from the 02 sensor. #49 is your ground off of the ecu for your 02 sensor. Also, the color of the wire to the ecu is og/p (orange/pink) #29. i hope that is the information you were looking for. Again, these wires are the ones that go to the ecu for the 02 sensors..........later, hotwheels of turborides.com

thanks a lot, just what i needed, thanks jay

aight well i pulled my computer out and searched through all the wires. i could not ind an orange/ pink wire. r u sure that was for a 90 mustang gt computer, 5 speed, oh well since it will be easiest just to connect it to the o2 sensor, which wire do i connect it to
