So im looking to put in my air/fuel ratio guage. Just wanted to know if i need the seperate sensor from autometer to install my air/fuel Guage.
Its the C2 Full sweep electrical if that helps.
Thanks

THe gauge should come with all the parts you need, I would believe.
If its a narrowband, just tap into your 02 sensor wire. (useless gauge imo)
If its a wide band you would have to weld a bung and install the wide band 02 sensor, i believe 12 inches away from the exhaust manifold angled downwards.
or just replace the oem wideband and send the 0-5 v signal off the guage too the ecu side of the o2 sensor 
haha
but it shouldve come with a new o2 sensor, and more than likely it wont fit in the factory hole
