have a afr meter ,how do i wire it in ? has 3 wires coming from the gauge grey/black/red where do these wires go to ? i think the black goes to the black on the lamda sensor ,but thats about as much as i know ,the gauge is a auto gauge brand cheers mark

 

An educated guess would be that...

Red is 12v switched ignition live
Black is earth
Grey is Narrowband lambda signal 0-1v

 

cheers for reply ,that means the grey wire should be connected to the lamda sensor any idea which is the signal wire off the lamda ? mark

 

connect it from lambda wire that goes to the ecu under your footwell

 

sorry feeling thick, what colour wire do i connect the grey wire to coming off the lamda sensor ,do i trace that wire back to ecu and connect it there , why not in engine bay straight off sensor . cheers mark PS thanks for reply andy
