Thread: Need help hooking these up

I just bought these two gauges




I have no idea how to hook these up! When you look at the back, the temp meter looks like this

and the afr meter looks like this
can i use my 02 sensor on the j pipe to run this thing? I have no idea how to hook either of them up and any help would be apreciated.

I never hooked up a water temp guage but I did hook up a A/F ratio guage and it was really easy red goes to a switched ignition source black is ground and the purple wire goes to I forget which wire on the O2 sensor. I hope you just using that thing for looks though cause thats all its good for. Man I can't believe people still using those things.

i was planning to use it with a safc. Should i not? i got an awesome deal on it, both gauges and a dual pod for $30.00

Those AFR guages are as specific as cel are. They are no help whatsoever. Get a wideband that will be your best bet, other than that its just a light show.

LOL!!!!!! very true. I can't tell how many times I blew up my Mazda MX-6 turbo when I used to use that chit. Now its AEM UEGO all the way and FTW.

thanks for the save guys, should i at least hook this up til i can afford a wideband? i dont even have a safc yet, which should i get first?

Get them both at the same time, Or get a wideband and a calum programmable ecu.
*tune with a laptop, piggybacks arent the best btu they work
