When i hook up the wire to the o2 sensor, th gauge won’t read, but as soon as i take the wire off it read super rich. when i unhook the connector and plug the o2 sensor directly to the wire i get the proper read… Some on help… how come i can’t hook the connector up w/o loosing the read on the gauge…
on another note…
does any one know of any instruction on how to install a Oil Pressure gauge 
thanks…
speaking of the a/f guage… where did you connect the power wire… and what did you use for ground thanks
I just installed an Autometer one into my Teg, you get power from black with a yellow trace at the key and earth some where solid like the kick panel. The O2 sensor is the white wire coming out of the sensor after the connector plug. black wire from the sensor, goes into a connector plug, then it turns white.
It works great.
