i need to find out what wire on the oxygen sensor to tap into for the air fuel gauge i was told white but its obviously the wrong one cause i'm not getting a reading, although i did ground my two gauges together so that could possibly be it any in-puts please!

 

Who's the company that makes the gauge, if autometer just call them and they'll tell you.

 

It's the white wire. Re-ground it somewhere else, check you power wire, and check your fuse.

 

alright thanks
