How many wires 1 ,3 or 4 and colours on lambda sensor? on most lambda sensors the Black wire is the sender wire but on yours I`m sure its blue ,as for the tacho gauge you need a wiring diagram for the ECU as you need to connect it there or pull the dash clocks out (carefully)
Hi again if you`d said you were fitting an FC commander the insructions are in the box it came in with ecu wiring diagrams telling you where to splice into the wires at ecu and the colour codes or pin numbers you need to solder and heat shrink the connections do not use scotch locks as it will cause you problems.and yes the blue wire is the signal wire coming out of the lambda sensor.if you do not have an ecu wiring diagram i will try and find the pin numbers for you.
