I have a boss welded into the exhaust just before the silencer and a pair of connections for the 12v feed hidden under the dash. The meter is one of these http://www.dtmpower.com/fuelmeter
Very handy for ensuring that the mixture is acceptable. When not in use the whole lot is unplugged and the threaded boss is blanked off. It's handy that Lambda sensors use an 18mm spark plug thread so a cut down spark plug with a 1931 half penny soldered on provides blanking. Sadly I didn't have a vintage coin to hand
