I just installed an Autometer A/F gauge, but it is not turning on. I hooked black wire to ground, red wire to 12V ignition, and purple wire to the O2 wire off of the ECU. The gauge is not doing anything at all. All of my connections are good. Any ideas would be greatly appreciated. Thanks

 

red to constant switched power?

 

faulty guage perhaps?

send it back.........

 

Yeah I guess it must be faulty. Back to Summit.

I'll bet you tapped the wrong wire.

 

I tapped the PO2 wire C18 ECU is the P30. With a voltmeter this wire puts out readings from around .2 to 1 volt which is correct.

 

should be a white wire

 

yeah it is a solid white wire

 

That gauge is not accurate at all. Sell it.
