Contour Enthusiasts Group Archives Forums General Troubleshooting O2 sensor wires

im instatling a air fuel ratio gauge, everything is hooked up but i dont know where the klast wire goes, all the instructuions say is to hook it to the 0 to 1 O2 sensor wire, but that didnt work so i cant be right, does anyone know where the right wire is.

come one someone has to have a air fuel ratio gauge

Don't know what you have if you don't say.

Ground
+12 volts
4 wire cable to the O2 sensor

What else do you need? Does it monitor something else?

Need to hook up to both O2 Sensor to able to read, because it is a V6, so you either need 2 air/feul gauge, or need a switch for the ONLY one gauge, switch which will show one side of the reading when switch to the other, shows the other side of the reading.
But don't you think it is just a toy, no use at all.

actually i will get use out of it it will tell me if im to lean, im putting nitrous on it, trying to be as safe as possible. i have a freind that just blew his motor on nitrous b/c he just ran right into it not taking the right pricausions, im not going to do what he did.

JUst hooked one up few weeks ago,,post on cali site or look for myfastse,,he helped me install mine,,i know that you need to splice into the wires on the left side of the UIM,, its a white wire with either a red or orange stripe,,can find out more for you later if you need. And you need to splice in as close to the sensor as you can get it. Thats the info i was given when we did mine,,i have the autometer gauge,, mounted it under my radio.
