Default air/fuel gauge

Anyone know all the components needed to install an air/fuel gauge on a 91 gt mustang? I hear you need more then just the gauge to have it read right? Also I'f you know all that is needed can you let me know where to get it. Thanks

don't get one. they don't actaully read your air/fuel ratio. they just read when your o2 sensors switch from rich to lean.

well id say its worth it since it does read the O2 since you could be lean and have issues that isnt good at all

They're really just a light show since 1V O2 sensors only accurately measure at 14.7:1 and a little both ways...
