I was wondering if anyone could please give me directions on how to hook up an air/fuel gauge and a water temp gauge, thanks

LIMaxin

anyone? i havent been able to find any help. all i found was on fastmaxima.com it said the air to fuel gauge can be tapped into pins 50 or 51 but i was wondering if it could just be tapped into an oxygen sensor under the hood. also i heard that if i were to tap the water temp gauge of the stock one it could mess up the readings from the ecu ( this is what one shop told me) i was just wondering if this was true as well. any help would be greatly appreciated

You could tap in the engine compartment but you'd be doing more work running the wire...

H2O temp has a separate sender and you would need a separate part like this:

where could i get something like that?

the gauge is electrical by the way,

You can try Omori (which I have) or HKS below:

It will depend on the Guage you have (and the thread pattern of the sender with it)...

I forgot which hose size we use, though. 1MAX2NV may remember... Good luck.

i tap in my oxygen sensor for my air/fuel gauge.. took like 15 mins no biggie.ran 1 wire and that was it.

LIMaxin

well i tapped into the oxygen sensor to hook up my a/f just now and its not accurate at all. it sits in the middle and when i give it half throtle gas it just goes all the way rich. And the water temp gauge is eletrical and the one you have posted there looks like its not.

you need wide band o2 for it to be accurate, are you boosted why do you need it?

And what the hell is piggy back chip, if it's from ebay or some**** like that it would be in best of your interests to take it off.

sounds like you tapped in to the wrong wire mine works perfect.what gauge are you using for the a/f if its autometer. all you have to do is email them adn tell them what year and type of car and they tell you what wire to tap into

LIMaxin

its an autotechnic gauge. i dont see how it could be the wrong wire, i tried all 3 coming from the o2 sensor and this is the only one giving a reading.

The A/F will bounce back and forth AFTER the engine warms up a bit. And yes, as the other person pointed out, w/o a wideband sensor, AF Meter isn't too accurate. For NA it's not useful unless you are squeezing.

Hope you didn't fry your guage randomly tapping the wires... One is 12V.

Doesn't matter if whether it is mechanical or electrical because you still need to "tap" into the coolant somewhere... unless you feel like drilling out some metal where the original is and risk getting metal shavings into the cooling system.

LIMaxin

ok well
1) where can i get a wideband sensor and how is it installed?
2) i know that i have to tap into the coolant somewhere but where can i find one that works with an elctric gauge because the one in that picture doesnt seam to be electric, how does it convert the signal?

Why do you need to hook up a water tempture gauge. I thought we had one of those already in the factory gauge cluster. You'd be better off installing a oil pressure gauge instead of having 2 water temp. gauges. The A/F ratio gauge needs to be connected to the blue wire on the O2 sensor.

LIMaxin

ya i hooked it up to the blue wire and the readings arent accurate at all, at half throtle it just jumps to all the way rich. well the gauge is actually an oil temp gauge but instead of buying a sending unit i was just going to tap it off the water temp, but i might as well just buy an oil temp sending unit. does anyone know where i can purchase one of these? thanx

are you boosted? because if you are not it's just stupid to spend you money on those things. Really, save it up.
