what wires are needed for the O2 sensor on my 4age bluetop? i know theres a wire which goes to #2 pin on the ECU. are there any other wires i need? and also will a sensor off any vehicle work? mine was broken off while getting couriered...

cheers

Just make sure that the sensor is same type as bluetops one, you even can use 3/4 wired sensors instead of 1 wire, just hook up heater wires to ignition switched power/ground... make sure you don't connect the sensor wrong way as you might damage it.

ok ive got the sensor of 4ageflyer now and its different to the one i had before - the extractors are aftermarket ones though. only issue now is ive got two yellow single pin plugs on the end of my loom and they both go to the O2 pin on the ecu...
only one of these plugs fits the plug on the O2 sensor though, but whats the other one for? do i need it for anything? or is meant to go to the ign or something?

probably other yellow plug is old skool diagnostic... leave it like it is... unless you have an diagnostic plug already, then I don't know.

ok cheers, any reason why it would be connected to the O2 pin though?
