A flash of inspiration and the help of an excellent local mechanic (Jesse James, newport Shropshire) and the points given by you wonderful posters.
The bike is now supporting the UK/4TX ECU and the lights work.....

So for all those with an import Japanese TDM850 marked as a 5GG - this has worked for me

1 Obtain a 4TX ECU marked with and E
2 Remove and replace 5GG ECU
3 Remove speed sensor from the speedo assembly - tape up under the front fairing
4 Remove the odd relay from above the ECU unit (white with four wires)
5 Bridge output of relay with a fused link - we used 7.5 amp
6 Smile lots with what appears to be a full power bike with working lights

It appears the imports are restricted in two areas - speed sensor for the 180 kph restriction and a programming restriction in the ECU unit

Again thanks to all those who helped.... good.gif rolleyes.gif

this example also used UK spec clocks (rev, tacho, temp etc)
