Fitting a 5 wire wide band lambda sensor in place of 3 wire
Installing a 5 wire wide band lambda in place of a standard 3 wire narrow band to a classic Impreza turbo with mapable ecu.
Original 3 wire lambda - positive, ground, signal to ecu.
New 5 wire wideband - ?
All help appreciated!

Most Widebands will have 2 outputs from their controller which may be useful to input into your aftermarket Ecu for closed loop fueling -
0 to 5 volt Wideband linear output and 0 to 1 volt simulated narrowband output.
If you intend to use a 0-5v input into your aftermarket Ecu then typically there's just one signal wire to connect and usually a reference ground
You'll need to calibrate this input into your Ecu, usually by means of a range and offset scale

Unless you have a syvecs, it's not as simple as connecting a 5 wire lambda into the Ecu.

The wire colours on new bosch sensor are red, black, yellow, grey, white if you would know which is which?

You're approaching this the wrong way. You cannot just buy a wide band sensor and wire it up in place of your narrow band using the stock wiring.
I've bought an Innovate LC2 the sensor plugs into a wide band controller. The controller then has two out puts. One to a gauge and the other is a configurable output that can either out put as Wide band to an after market ECU or simulated narrow band to one.
If you're trying to wire up a wide band for use with a stock ecu then I think you need to rethink what you're trying to do.
