MG MGB Technical - MGB Tacho help?

Hi all,
I have a RVC 1414/00F tacho from an MGB that I want to fit in my midget.
Could some kind soul tell me what wiring goes to the Brass lug , and what wiring goes to the terminal right next to it?
for some reason or other, I can't upload a photo.
Cheers colin

I expect your photo is too large. Shrink it down to less than 1 MB and try again.

Hi Mike,
Many thanks for that tip re shrinking the photo!
So , its the brass lug marked A and the terminal marked B that I need to know about.
Cheers & thanks

This should be an RVI 1440/00F as fitted to RB cars, CB are similar but have the hole for the ignition warning light.

The signal wire (black/white on an MGB goes on the post, and the 12v supply (green) goes on the insulated spade.

The earth wire normally goes on the spade on the case, but if the wiring has the through-hole terminal that can go on one of the studs as per the CB tachs.
