Hey guys my ProSport Wideband just turned up seems pretty straight forward to fit although I need to ask which colour wires go where as I cant remember.

The POWER loom has the following colour wires:
Red is obviously 12v live
Black is ground
Orange- Ignition live????
White- Illumination?????

There is also another plug which goes into the control unit with a green, brown and black wire. According to the poor instructions:
Black is ground
Brown is Wideband analog output 0v-5v
Green is Narrow band analog output 0v-1v

Do I need to wire in the narrowband wire? And what pins do these go on the ECU?

Also when calibrating it does the car need to be upto temperature and running?

Thanks Lewis

if your using this on the stock narrowband sensor then its a waste of time.

orange and white are most probably illumination power and ground.

No I have the bosch sensor aswell, so thats why I asked is there any need for the green narrow band wire to be wired in?

If not, where on the ECU does the brown wire for the wideband go?

the green one can be wired to replace the standard narrow band if u want, but really has no point, i have run my car for a good 6 months now with no standard O2 sensor and it runs fine, it just sets a specific closed loop setting and stays on the closed loop mapping all the time...

dont get what you mean mate? The sensor looms are all plug and play, apart from the power loom obviously becuase it has to be spliced into the car loom, its just this other loom with the green, brown and black wire which is confusing me, dont know what to do with the wires.

analog feed is to feed an ECU as long as it can read a 0-5v feed, it can be used for autotune on some ecu's or for rich and retard (safety mode, or limp mode if setting go outside operation perameters)
