Mark II Light Switch

[1342FS]

Can anyone help with the wiring of a Mark II light switch please? I have replaced the original 57 year old switch with a replacement from SNG Barratt. The wiring diagram they provide does not seem to be anything like the order of the original Workshop Manual or separate wiring diagrams such as that provided by Coventry Auto Components. ]Has anyone successfully fitted the Barratt replacement switch C20246?

The “original” clockwise order starting with the Brown/White feed from the Control Box B terminal is: 6 Brown/White; 10 Green to A4 & Yellow/Purple to Overdrive Switch; 12 Red/Yellow to Fog Lights; 13 Blue to Dipper Switch; 2 Red/Black to Overdrive Warning Light and 4 Three Red wires to Panel Light Switch, Side Lights and Map Switch.

The C20246 from Barratt’s in the same order clockwise is: D Brown/White from Control Box; E Green from A4; F Red x3; G Red/Yellow Fog Lights; A Blue to Dipper Switch; B Blank; C Red/Black Overdrive Warning Light.

I have asked the supplier SNG Barratt but they only say “follow the fitting instruction”
Thank you in anticipation
